What is Pelagios?

A DecentralisedCommunity & Infrastructure

for Linked Open Geodata in the Humanities

4

Connectivity through common references rather than a common schema

What Pelagios isn’t | One ring to rule them all

Not a data aggregator

Not a repository

Not a standard data model

The concept | Don’t Unify the Model – Annotate!

Things we’ve learned | 1. Open partnerships are more efficient than closed consortia

Linking data is a social process:

•Involves multiple datasets, organisations, roles

•Inertia in one area has knock-on effects in many others

•Restricting visibility in one area reduces impact in others

•Greater likelihood of failure due to policy decsions

•Open partnerships more likely to:

• Attract new members

• Drive sectoral change

Stuff we’ve learned | 2. Speed-reading?
