Growing the Graph | #2 Linking Gazetteers
Associating Places with Places (in different gazetteers).
Pelagios is a gazetteer user
Pelagios is not a maintainer or aggregator of gazetteers
PS: Should we unify rather than align? We don‘t think so!
Good reasons for diversity! Coverage, granularity, focus, scholarly
quality, community, …
Pelagios 3 defined an RDF profile (or »specification«) for
1. publishing links between places in different gazetteers online
2. publishing minimal place metadata online
So that we search at all!
So that we can make
connections and cross-search.
INGEST & ADMINISTRATION
are place groups
Unified fulltext search
across both indices
Fuzzy search support
(building the links)
and lookup tables
(to speed things up)RDF
JSON(P) + CORS HTML
Items in dataset, sub-items in item
Places per dataset, per item
Temporal profile of dataset
Subsets in dataset
closeMatch-network for place
Datasets per place (with or without closeMatches)
WORK IN PROGRESS!
