ORKG weekly snapshots

This dataset contains two archives:

• orkg.tar.gz: 34 weekly snapshots of the Open Research Knowledge Graph (ORKG), exported in N-Triples (.nt) RDF format. The snapshots were collected automatically on a weekly basis and cover a consecutive period of 34 weeks. Each file (1.nt through 34.nt) corresponds to a full dump of the ORKG knowledge graph at the time of export, enabling longitudinal analysis of the graph’s growth, evolution, and change over time.
• alldata.TB.nq.gz: a versioned dataset containing the triples from all 34 snapshots with an IRI in the fourth position (quad) containing all versions in which the triple is valid (BEAR versioning approach)

The timestamps from which the snapshots originate are: 20250515, 20250522, 20250527, 20250608, 20250612, 20250619, 20250626, 20250703, 20250710, 20250717, 20250724, 20250731, 20250807, 20250814, 20250821, 20250828, 20250904, 20250911, 20250918, 20250925, 20251002, 20251009, 20251016, 20251023, 20251030, 20251106, 20251113, 20251120, 20251127, 20251204, 20251211, 20251218, 20251225, 20260129
