About

==========================================================

Highlight 1: An old record is not a data but now defined as a new semantic dataset.

  • i.e. its triples, graphs, links, file formats ...
  • i.e. its revised, vocabulary encoded versions ...
  • ex. data:d2148340 a dcat:dataset. #files:json-ld, ttl, XML

Highlight 2: A new method to curate, publish & visualize LOD graphs via CKAN portal.

  • i.e. two models for one dataset published in two views.
  • ex. data:d2148340. # Dublin Core @schema1
  • ex. data:d2148340 a data:Refined. # more semantics@schema2

Highlight 3: Validation & Reproducibility: Provenance and Contexts are in details.

  • Currently records from 74 agents who have roles in NGO (2), Museum (5), Library (2), Government (9), Archive (1), and Academia (55).

Total Resources:

  • 843,309 records from 14 datasets.
