Initially, Type Indexes were discussed and worked on together with the WebId Profile Spec. During this work we came to the conclusion to separate the index topic from the webId profile. The igniting issue is documented here and decision discussions were conducted at the WebID weekly meetings respectively here and here.
Further conversation on this work is discussed on the WebId profile gitter chat and weekly meetings. Feel free to open a GitIssue in this repo if you want to contribute or have a remark/improvement suggestion/concern.
...first and foremost, trying to simply document what-is. This means, we are documenting how type indexes are implemented and used NOW.
We have taken into account the initial proposal in our current work.
...might build on top of this spec. We started collecting ideas on a dedicated git ticket. If you want to start discussion on one of those ideas, feel free. In order to have them considered for future iterations of this document please label the ticket with discussion and future iteration please.
...might speak about other types of indexes, in their own dedicated repositories.
