Make a Project Proposal / Schedule

[tkw1536]

We should organize new and existing issues, and come up with a (somewhat concrete) plan on what to do with MathDataHub.

Some minor ideas:

• @katjabercic had a vision in mind where we have a "portal for discrete objects" with a couple of very well-interlinked objects
• lots of features (querying etc) that are easy to do in our data model, but have not been implemented (to be made into distinct issues)
• @kohlhase suggested if we can be concrete enough and gain external collaborators it might be worthwhile to actually apply for funding with e.g. the EU

We should afterwards present the schedule (and have discussions) in the KWARC group and maybe elsewhere.

With the following steps, we can wrap up the new version.

1. Start with describing the new data model.
2. Import at least one more dataset, as a use case for cross-dataset querying (see the issue below for a dataset suggestion).
3. Implement cross-dataset querying.

We can aim towards a portal for symmetric discrete objects as a more long term goal.

In addition to the core set of features listed above, we should also work on the following.

• Codec documentation,
• exports and downloads.
