Re: Use the void and schema.org [Was; Re: LODAtlas 1.0 release - Browsing Linked Data Catalogs]

Thanks Armando.

In LODAtlas, we are particularly interested in the links between datasets, and showing them to users so that they understand how a dataset fits in the whole cloud. That’s why we use old.datahub/lod-cloud data in the first place. Is there also support in the sort of tools you mention to declare what datasets the one of interest links to?

best,
Emmanuel
