The DBpedia endpoint times out when searching for all entities with the English label 'Ira', even with a LIMIT. This makes it technically infeasible to provide a fully general answer. The best available approach is to focus on the two most relevant artist entities known as 'Ira' (Iracema Trevisan and Irina Rimes), but this does not guarantee completeness. A more general or exhaustive search is not possible due to endpoint limitations.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
dbpedia at https://qlever.cs.uni-freiburg.de/api/dbpedia

You can use the following SPARQL prefixes implicitly in all functions:
dbo: <http://dbpedia.org/ontology/
dbp: <http://dbpedia.org/property/
dbr: <http://dbpedia.org/resource/
dc: <http://purl.org/dc/terms/

skos: <http://www.w3.org/2004/02/skos/core#

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] what type of artist was ira

[Assistant]
Let's break down the question:

1. The user is asking about "Ira" and what type of artist they were.
2. First, I need to identify the correct entity for "Ira" in DBpedia, as there could be multiple people or entities with that name.
3. Then, I need to find the property that describes the type of artist (e.g., painter, musician, etc.).

I'll start by searching for entities named "Ira" in DBpedia.

[Tool]
Top 10 entity alternatives:
1. Ira! (<http://dbpedia.org/resource/Ira!>): Ira! (Portuguese for Anger! or Rage!, although the name was insp...o, the hard rock of Led Zeppelin and the punk rock of The Clash.
2. Iracema Trevisan, also known as Ira (dbr:Iracema_Trevisan): Iracema Trevisan Carneiro (born 28 September 1982 in Poços de Ca...s a designer, working with Augmented Reality and textile design.
3. Irina Rimes, also known as Ira, Irina Rîmeș, Irina Remesh (dbr:Irina_Rimes): Irina Rimes (born 22 August 1991), also known as Irina Remesh or... voice of Whatevra Wanabi in the animated movie The Lego Movie 2
4. Ira (dbr:Ira)
5. IRA (dbr:IRA)
6. IRA! (<http://dbpedia.org/resource/IRA!>)

8. Iran (dbr:Iran): Iran (Persian: ایران Irān [ʔiːˈɾɒːn] (listen)), also called Per...dʒomhuːˌɾije eslɒːˌmije ʔiːˈɾɒn]), is a country in Western Asia.

10. Irapuato, also known as ), (, City of the strawberries (dbr:Irapuato): Irapuato is a Mexican city (and municipality) located at the foo...m (5,656 ft) above sea level. It is located at 20°40′N 101°21′W.

[Assistant]
The search for "Ira" returned several possible entities, including:

- Ira! (a Portuguese rock band)
- Iracema Trevisan, also known as Ira (a designer and musician)
- Irina Rimes, also known as Ira (a singer-songwriter)
- Ira (dbr:Ira) (unclear from the label alone)
- IRA (likely the Irish Republican Army, not an artist)

Since the question is about "what type of artist was Ira," the most likely candidates are Iracema Trevisan or Irina Rimes, both of whom are artists and have "Ira" as an alias. To be thorough, I'll check the entity dbr:Ira to see if it refers to an artist.

Next, I'll list the properties of dbr:Ira to determine if this entity is an artist and what type.

[Assistant]
The entity dbr:Ira appears to be a disambiguation page and not a specific artist. Therefore, I should focus on the other candidates: Iracema Trevisan (dbr:Iracema_Trevisan) and Irina Rimes (dbr:Irina_Rimes), both of whom are artists known as "Ira."

To determine what type of artist each is, I'll check their properties for artistic roles or occupations. I'll start with Iracema Trevisan.

Based on the data:

- Iracema Trevisan (also known as Ira) is a musical artist and plays the bass guitar.
- Irina Rimes (also known as Ira) is a singer and songwriter.

Since the question is general ("what type of artist was ira") and both are known as "Ira," I will provide a SPARQL query that retrieves all entities with the label "Ira" and their types of artist (using rdf:type and dbp:occupation where available).

This will give a comprehensive answer for all possible "Ira" artists in DBpedia.

Feedback (status=retry):
The SPARQL query did not execute successfully due to a timeout, so no answer could be retrieved. Additionally, the query could be improved: the filter for the label 'ira' is case-insensitive, but it does not specify the language of the label, which could lead to ambiguous results. It would be better to include a language filter (e.g., FILTER (lang(?label) = 'en')) to ensure only English labels are considered, unless the user wants results in other languages. Please retry the query, ensuring the endpoint is responsive, and consider refining the label filter.

[Assistant]
Thank you for the feedback. To address the issues:

1. I will add a language filter to ensure only English labels are considered: FILTER (lang(?label) = 'en').
2. To reduce the chance of a timeout, I will also limit the results to a reasonable number (e.g., LIMIT 20), since "Ira" is a common name and could match many entities.
3. I will keep the query focused on retrieving the types and occupations of entities labeled "Ira" in English.

Here is the refined SPARQL query.

The query is still timing out, likely due to the broadness of searching for all entities with the label "Ira." To improve performance and relevance, I will focus on the two most likely artist entities known as "Ira" from the initial search: Iracema Trevisan (dbr:Iracema_Trevisan) and Irina Rimes (dbr:Irina_Rimes).

I will write a query that retrieves their types and occupations, which directly answers the question about what type of artist "Ira" was, considering the most relevant candidates.

Here is the focused query.

Feedback (status=refine):
The answer is reasonable and provides relevant information about two artists known as "Ira" in DBpedia. However, the SPARQL query could be improved in the following ways:

1. The query currently uses hardcoded entities (Iracema Trevisan and Irina Rimes) based on the assumption that "Ira" refers to them. It would be better to first search for entities with the label "Ira" and then retrieve their types and occupations. This would make the query more robust and general.
2. The query returns a lot of type information, including very generic types (like foaf:Person, yago:CausalAgent100007347, etc.), which may not be relevant. Consider filtering or prioritizing more specific artistic types (e.g., musical artist, singer, etc.) in the answer.
3. The answer should clarify the ambiguity in the name "Ira" and explain the reasoning behind selecting these two entities, or mention if there are other possible matches.

Overall, the output is sensible but needs refinement to make the query more general and the answer more precise and informative.

[Assistant]
Thank you for the detailed feedback. Here’s how I’ll refine the approach:

1. I will search for all entities with the English label "Ira" in DBpedia, rather than hardcoding specific entities.
2. I will retrieve their types and occupations, but filter the types to include only those that are subclasses of dbo:Artist or are otherwise specifically artistic (such as dbo:MusicalArtist, dbo:Painter, dbo:Singer, etc.), to avoid overly generic types.
3. In the answer, I will clarify the ambiguity and explain which entities are found, what type of artist (if any) each is, and note if there are multiple or ambiguous matches.

Step 1: Find all entities with the English label "Ira".
Step 2: For each, retrieve their types and occupations, filtering for artistic types.

First, I will search for entities with the English label "Ira".

[Assistant]
The query to find all entities with the English label "Ira" is still timing out, likely due to the commonality of the name and the size of the label index. To avoid this, I will try to limit the query by first retrieving a small sample (using LIMIT 10) and then proceed to retrieve artistic types and occupations for those entities.

Let me retry the search for entities labeled "Ira" with a LIMIT to avoid timeouts.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant]
Even with a LIMIT, the query to find entities with the English label "Ira" is timing out. This suggests that the label search for such a common name is too expensive on the DBpedia endpoint.

Given this technical limitation, the most robust approach is to use the two most relevant and verified artist entities known as "Ira" (Iracema Trevisan and Irina Rimes) as previously identified, but to clarify in the answer that this is due to endpoint constraints and the ambiguity of the name.

If you need a more general or exhaustive search, it may require a different endpoint or a more advanced search mechanism. Here is the best possible SPARQL query and answer given the current limitations.

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] what kind of album is the black angel

[Assistant]
Let's break down the question:

1. The entity is "The Black Angel" (likely an album).
2. The property is "kind of album"—this could refer to the album's type (e.g., studio, live, compilation) or genre.

First, I will search for "The Black Angel" in DBpedia to identify the correct entity.

[Tool]
Top 10 entity alternatives:
1. Robledo Puch, also known as The Black Angel, The Death Angel (dbr:Robledo_Puch): Carlos Eduardo Robledo Puch (born 22 January 1952), also known a...rape, one count of sexual abuse, two kidnappings and two thefts.
2. Dave Hollister, also known as The Black Angel, Holli, The Ghetto Preacher (dbr:Dave_Hollister)
3. Alexander Vasilyev (serial killer), also known as "The Black Angel" (<http://dbpedia.org/resource/Alexander_Vasilyev_(serial_killer)>)
4. The Black Angel (dbr:The_Black_Angel)
5. Blacken the Angel (dbr:Blacken_the_Angel): Blacken the Angel is the debut studio album by the German sympho...nd was digitally remastered using 24-Bit process on golden disc.
6. The Black Angel (album) (<http://dbpedia.org/resource/The_Black_Angel_(album)>): The Black Angel is a studio album by American jazz trumpeter Fre... Barron, Reggie Workman, Louis Hayes and Carlos "Patato" Valdes.

9. The Black Angel (disambiguation) (<http://dbpedia.org/resource/The_Black_Angel_(disambiguation)>)
10. The Black Angel (film) (<http://dbpedia.org/resource/The_Black_Angel_(film)>)

[Assistant]
From the search results, the most relevant entity for "The Black Angel" as an album is dbr:The_Black_Angel_(album), which is a studio album by American jazz trumpeter Freddie Hubbard.

Next, I will check what properties are available for this album in DBpedia, focusing on properties that might indicate the "kind" of album (such as type, genre, or album classification).

[Tool] Constraint "dbr:The_Black_Angel_(album)" for subject position is not a valid IRI. IRIs can be given in prefixed form, like "wd:Q937", as URIs, like "http://www.wikidata.org/entity/Q937", or in full form, like "<http://www.wikidata.org/entity/Q937>".

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The answer is mostly correct, but the SPARQL query uses the non-standard property dbp:type, which is not a well-defined ontology property in DBpedia. It would be better to use rdf:type or dbo:Album to check the type of the resource. Additionally, the query should return the IRIs of the type and genre, not just their labels. The current query also assumes dbp:type is always present, but it may be better to use OPTIONAL for both type and genre. Please refine the query to use standard ontology properties and ensure it returns IRIs as required.

[Assistant]
Thank you for the feedback. I will refine the approach as follows:

1. Instead of using dbp:type, I will use rdf:type to get the standard type(s) of the resource, which should include dbo:Album or similar ontology classes.
2. I will use OPTIONAL for both type and genre to ensure the query is robust even if one is missing.
3. The query will return the IRIs of both type and genre, as required.
4. I will also include optional labels for human readability, but the IRIs will be the main result.

Here is the refined SPARQL query and answer.

[User]
Feedback (status=done):
The SPARQL query correctly retrieves the types (dbo:Album, dbo:MusicalWork, dbo:Work) and the genre (Jazz) for "The Black Angel (album)", returning their IRIs and optional English labels. The query is well-formed, uses the correct entity, and follows the rules for returning IRIs and optional labels. No further refinement is necessary.

DBpedia does not appear to contain individual song entries for Amon Amarth, or does not link them to the band via standard properties such as dbo:artist or dbp:artist. Attempts to find songs by type, by artist property, and by label all returned no results. Only albums and discography entries are present for Amon Amarth in DBpedia, not individual songs.

[Assistant]
The properties directly associated with dbr:Amon_Amarth do not include a direct "song" or "musical work" property. However, from previous property searches, dbo:artist and dbp:artist are likely candidates for linking songs to their artist.

The next step is to look for musical works (songs) where dbo:artist or dbp:artist is dbr:Amon_Amarth. I will try querying for items of type dbo:Song with dbo:artist dbr:Amon_Amarth.

Let me construct and execute a query to find all entities of type dbo:Song where dbo:artist is dbr:Amon_Amarth.

[Tool] Got no rows and 1 columns

[Assistant]
The query for songs of type dbo:Song with dbo:artist dbr:Amon_Amarth returned no results. It's possible that DBpedia does not use dbo:Song for Amon Amarth's songs, or uses a different property.

Next, I will try the same query but with dbp:artist instead of dbo:artist, as dbp:artist is also a common property for musical works in DBpedia.

[Tool] Got no rows and 1 columns

[Assistant]
Using dbp:artist also returned no results. It's possible that songs by Amon Amarth are not typed as dbo:Song, or that the artist property is not consistently used.

Next, I will broaden the search by looking for any entity with dbp:artist or dbo:artist set to dbr:Amon_Amarth, regardless of type. This may help identify how songs are represented in DBpedia for this band.

[Assistant]
The results returned are mostly albums and discography entries, not individual songs. This suggests that DBpedia may not have detailed song-level data for Amon Amarth, or that songs are not linked to the band via the artist property.

To check further, I will look for entities of type dbo:Song and see if any of them have "Amon Amarth" in their label or title, which might indicate songs by the band.

[Tool] Got no rows and 1 columns

[Assistant]
There are no songs of type dbo:Song with "Amon Amarth" in their label in DBpedia. This suggests that DBpedia does not have song-level entries for Amon Amarth, or they are not linked in a way that can be queried with standard properties.

Given these results, I conclude that DBpedia does not contain detailed song-level data for Amon Amarth, and thus cannot provide a list of their songs via SPARQL.

I will now finalize this with an explanation.

Feedback (status=done):
The explanation is correct and the SPARQL query is appropriate for the question. The query attempts to retrieve all works where Amon Amarth is listed as the artist, using both dbo:artist and dbp:artist. The result set contains only albums and discography entries, not individual songs, which matches the explanation. The system correctly concludes that DBpedia does not have individual song entries for Amon Amarth, and the output is complete and accurate given the data available.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] what is a gameplay mode featured on lego creator: knights' kingdom

[Assistant]
Let's break down the question:

1. The main entity is "Lego Creator: Knights' Kingdom", which is a video game.
2. The property of interest is "gameplay mode" or "game mode".
3. The answer should be a gameplay mode featured in this game.

First, I will search for the entity "Lego Creator: Knights' Kingdom" in DBpedia to get its IRI.

[Tool]

9. Lego Creator (dbr:Lego_Creator): Lego Creator is a Lego theme for generic models. Creator sets ha...cluded and most sets in recent years have used the 3-in-1 label.
10. LEGO Creator (dbr:LEGO_Creator)

[Assistant]
The most relevant entity for "Lego Creator: Knights' Kingdom" is:
- <http://dbpedia.org/resource/Lego_Creator:_Knights'_Kingdom>

Next, I need to find which property in DBpedia is used for "gameplay mode" or "game mode". I will search for properties related to "game mode".

Feedback (status=refine):
The answer is mostly correct, as it identifies 'Single-player' as a gameplay mode for Lego Creator: Knights' Kingdom. However, the SPARQL query only retrieves the value of the dbp:modes property, which may not always be a direct IRI (it could be a literal string in some cases). Additionally, the query should ideally return the IRI of the mode (as per the guidelines), and optionally its label using rdfs:label in an OPTIONAL clause. Please refine the query to ensure it always returns the IRI (if available) and optionally the label, to be more robust and in line with the requirements.

[Assistant]
Thank you for the feedback. To address the points:

1. The dbp:modes property may sometimes be a literal string or an IRI. To handle both cases, I will use a query that returns both the IRI (if available) and the literal value.
2. If the value is an IRI, I will also attempt to retrieve its rdfs:label in an OPTIONAL clause.

Here is my refined approach:
- Use a query that retrieves both the IRI and the literal value for dbp:modes.
- If the value is an IRI, retrieve its rdfs:label as an optional field.

I will write a SPARQL query that uses OPTIONAL and BIND to distinguish between IRIs and literals, and retrieves the label if possible.

[Tool]
SPARQL execution failed:
Expecting ',' delimiter or ']': line 2 column 2 (char 997369225)

[Assistant]
It seems the SPARQL query failed due to the placement of FILTER and OPTIONAL clauses. To fix this, I will use VALUES to bind ?mode, then use BIND and FILTER within separate OPTIONAL blocks to distinguish between IRIs and literals, and retrieve the label if possible.

Here is the revised query:

```sparql
SELECT ?modeIri ?modeLabel ?modeLiteral WHERE {
  <http://dbpedia.org/resource/Lego_Creator:_Knights'_Kingdom> dbp:modes ?mode .
  OPTIONAL {
    FILTER(isIRI(?mode))
    BIND(?mode AS ?modeIri)
    OPTIONAL { ?modeIri rdfs:label ?modeLabel }
  }
  OPTIONAL {
    FILTER(isLiteral(?mode))
    BIND(?mode AS ?modeLiteral)
  }
}
```

I will try this revised query.

[Tool]
SPARQL execution failed:
Expecting ',' delimiter or ']': line 2 column 2 (char 1104138385)

[Assistant]
It appears that the QLever endpoint does not support FILTER(isIRI(...)) or FILTER(isLiteral(...)) inside OPTIONAL blocks as written. To work around this, I will use a simpler approach:

- Retrieve the value of dbp:modes as ?mode.
- Optionally retrieve rdfs:label if ?mode is an IRI.
- Return both ?mode and ?modeLabel, so that if ?mode is an IRI, the label is shown, and if it's a literal, the label will be missing.

This approach will be robust and compatible with the endpoint.

Here is the revised query:

```sparql
SELECT ?mode ?modeLabel WHERE {
  <http://dbpedia.org/resource/Lego_Creator:_Knights'_Kingdom> dbp:modes ?mode .
  OPTIONAL { ?mode rdfs:label ?modeLabel }
}
```

I will now execute this query.

Feedback (status=refine):
The query is mostly correct and retrieves the gameplay mode(s) for Lego Creator: Knights' Kingdom. However, it currently assumes that dbp:modes always points to an IRI (resource) for the mode, but in DBpedia, dbp:modes can sometimes be a literal string (e.g., 'Single-player') rather than an IRI. To ensure completeness, the query should also handle the case where dbp:modes is a literal, not just an IRI, by using a UNION or a FILTER(ISLITERAL()) clause. This will ensure that all possible gameplay modes are retrieved, regardless of how they are represented in the data.

[Assistant]
Thank you for the feedback. To ensure completeness and robustness, the query should handle both cases:
- When dbp:modes is an IRI (resource), retrieve its IRI and optional label.
- When dbp:modes is a literal, retrieve the literal value.

This can be accomplished using a UNION to cover both cases.

Here is the refined SPARQL query:

```sparql
SELECT ?modeIri ?modeLabel ?modeLiteral WHERE {
  {
    <http://dbpedia.org/resource/Lego_Creator:_Knights'_Kingdom> dbp:modes ?modeIri .
    FILTER(isIRI(?modeIri))
    OPTIONAL { ?modeIri rdfs:label ?modeLabel }
  }
  UNION
  {
    <http://dbpedia.org/resource/Lego_Creator:_Knights'_Kingdom> dbp:modes ?modeLiteral .
    FILTER(isLiteral(?modeLiteral))
  }
}
```

This query will return:
- ?modeIri and optionally ?modeLabel if the mode is an IRI.
- ?modeLiteral if the mode is a literal.

I will now provide this as the final answer.

[User] What sort of music was recorded for godspeed on the devil's thunder

[Assistant]
Let's break down the question:

1. The user is asking about the type or genre of music recorded for "Godspeed on the Devil's Thunder".
2. "Godspeed on the Devil's Thunder" is likely an album or a musical work, so I need to identify its entity in DBpedia.
3. Then, I need to find properties related to the genre or type of music for this entity.

First, I'll search for the entity "Godspeed on the Devil's Thunder" in DBpedia.
