[Epic] Provide a set of useful queries

[Daniel-Mietchen]

Epic description in words:

This epic is to provide a set of queries that yield data that can be readily incorporated into mathematical research and teaching workflows.

Additional Info:

Useful queries require at least the following

• a use case, e.g. a research question or a teaching point
• functional query infrastructure, as demonstrated via feature queries (cf. [Epic] Provide a set of feature queries #345)
• data relevant to the use case
• documentation of query elements that are relevant to the example use case
• documentation of aspects of the query that may need adaptation for other use cases
• reproducibility, including in the context of dynamic data
• citability of the queries
• citability of the results
• provisions for data curation
• provisions for query curation

They serve several purposes

• documenting, testing, teaching and possibly advancing some aspects of mathematics, including relevant data, software or infrastructure

Corresponding Milestones:

• M-TA5-A3 API access possible.
• M-TA5-A4 Math specific data-types implemented.
• M-TA5-A5 External identifiers integrated.
• M-TA5-C1 Ontologies implemented.
• M-TA5-C2 MaRDI metadata standard for scientists and publications established.
• M-TA5-C3 MaRDI metadata standard for software and institutions established.
• M-TA5-C4 Process documentation on MSC assignment to MaRDI artifacts established.

Epic acceptance criteria:

• A set of at least 10 example use cases, of which at least 6 for research and at least 1 for teaching.
• At least one useful query for each use case, along with suitable documentation.
• For each useful query, one example of how it can be adapted to serve use cases that differ in specific ways.
• A mechanism that regularly checks that the queries perform as documented.
• Some mechanism allowing users to subscribe to some aspects of useful queries, e.g. dynamic changes to the results.

Checklist for this epic:

• the main MaRDI project has been assigned as project
• report has been created
