The ancient geography model

The ancient geography model

The ancient geography model

The “Pleiades part” ● No single authority “Pleiades” for ancient people ● Not feasible to create brand new authority ● Linked Data doesn’t require single silo

● Many existing authorities ○ LGPN, Trismegistos, PIR ○ PBE/PBW, Smith, Hellenistic Babylonia, RIB, Syriac, Nomisma,

Kerameikos ○ Perseus Catalog, VIAF, BM persons, Zenon catalog

● Get them into RDF ○ uris, properties, relationships ○ co-references

The “Pelagios part” 1. Enable and encourage linking to persons 2. Enable and encourage linking between datasets 3. Internal relationships:

a. person:1234 snap:hasBond <xyz> . <xyz> rdf:type snap:DaughterOf ; snap:bondWith person:7890 .

4. Unproblematic co-references: a. person:200000 rdf:type snap:mergedResource ;

dcterms:replaces person:12345 ; dcterms:replaces person 67005 .

● To merge or not to merge..? o Adding in the description of scholarly disagreement

on merging e.g V5a-38858 claims to be both pir2-r-0243 and pir2-

r-0244 V5a-38861 claims to be both pir2-i-0492 and pir2-

i-0493
