Date ranges / intervals

[akuckartz]

Are there or will there be support for date ranges, such as events between 2012-11-28 and 2014-02-05? In other words: will such filtering be done by the client or by the server (or are both possible)?

If it has not yet been decided: the example interval above could be devided by the client into such fragments:

• 2012-11-28
• 2012-11-29
• 2012-11-30 (and maybe 2012-11-31)
• 2012-12 (whole month)
• 2013 (whole year)
• 2014-01
• 2014-02-01
• 2014-02-02
• 2014-02-03
• 2014-02-04
• 2014-02-05

A client of basic Linked Data Fragments would have to do the filtering by itself, as basic Linked Data Fragments only allow to select triple patterns (no ranges). More specialized fragments could allow this on the server side.

However, support for such queries on the basic LDF clients would be possible, albeit slowly. Do you have example SPARQL queries and an example dataset?

I will have a sample dataset in a week or so.

EDIT: I have restarted working on this on 2017-10-21, but it will take some time.
