2. What? | Aims of Pelagios
Interlinking data about the Ancient World using Linked Open Data (LOD)
methods
Focus on place references (in maps, texts,
images, database tables)
Establishing simple “Pelagios Principles” to
support contributors in preparing
their data

5. How? | Don’t Unify the Model – Annotate!
The Pelagios Principles
I. Annotate your place references with appropriate entries in the
Pleiades Gazetteer
II. Publish annotations in the Open Annotation (OAC) RDF vocabulary

7. Why? | Example: The Graph Explorer
Exploring Relations between Exploring Relations between
Places through Data Data through Place

8. Challenges | Some Issues Identified So Far
Issues with automatic matching (data or in-house Gazetter)
Name-based matching based on Pleiades or Pleiades+ [1] toponyms
Followed by coordinate matching for verification/disambiguation
Granularity & vague references (South Italy, Greek Islands)
Location-based adjectives (Corinthian vs. Corinth)
Typing of place references
Find spot vs. origin, “depicts”, etc.
Uncertain references (probably made in…, from the vicinity of…)
[1] Pleiades+ toponym extension to Pleiades based on Geonames

9. Discussion | Annotation vs. Unified Model
The goal of Pelagios is to
create links rather than to aggregate and enrich
provide a toolkit & an API rather than a “single point of access”
Pelagios requests that partners map
data to a vocabulary rather than their metadata schema to another
The fact that Pelagios is limited in scope helps!
Restriction to Place
Very limited set of “primitives” – Dataset, (typed?) Annotation, Place
