The‘Seman3c Web’ ‘Linked Open Data’

  Data aggrega3on

  Federated search

  Standardiza3on of data representa3on

  Schema alignment

Connec3vity through common references rather than a common schema

What Linked Open Data enables| The Pelagios API

8

  Context – obtain links to online data that may be relevant to your own

  Discovery – users can find your data by following links on other partners’ sites

  Reuse – the Pelagios API provides machine-‐readable representa3ons (JSON, RDF) to enable mashups and other forms of 3rd party re-‐use

Pelagios API Tools | Widgets

9

Pop-‐up elements you can embed on your own Web pages to display data from the Pelagios partners

Pelagios API in the Wild | Open Context

10

A free, open access resource for the electronic publica3on of primary field research from archaeology and related disciplines hVp://opencontext.org

Result pages for Pleiades places show small sidebar boxes with references from the Pelagios API

Pelagios API in the Wild | awld.js

11

A JavaScript library for Ancient World Linked Data, developed by Nick Rabinowitz and Sebas3an Heath, awld.js adds func3onality and visual elements based on links to stable URIs. hVp://isawnyu.github.com/awld-‐js/

Pop-‐ups for Pleiades places link to Pelagios references

How to link data| The Pelagios three steps to heaven

15

1.  Make your data available over the Web with stable URIs

2.  Map your place references to the Pleiades Gaze]eer of the Ancient World1

3.  Publish place references as RDF

  Pelagios considers place references to be “annota3ons” on your data – use the Open Annota<on2 RDF vocabulary

  Use Vocabulary of Interlinked Datasets (VoID)3 for dataset metadata

1 hVp://pleiades.stoa.org/ 2 hVp://www.openannota3on.org/spec/beta/ 3 hVp://www.w3.org/TR/void/

Warning: that‘s the tough part!

Remember: this is separate from your data!

Challenges | Issues Iden3fied So Far…

  Aggrega<ng Data – no two datasets are the same (and we are only collec3ng place references…)

  RDF dumps – 1 dumpfile vs. 1.000s of dumpfiles vs. SPARQL

  How to label appropriately? (references, data containing the reference)

  Dataset par<<ons – no subsets vs. mul.ple levels of hierarchy

  Dataset versioning – if you update your data…

  Conceptualizing Data – how to express the rela3on between data & place

  Find spot vs. origin, “depicts”, etc.

  Uncertain references (probably made in…, from the vicinity of…)

  Granularity & vague references (South Italy, Greek Islands)

  Pelagios has been taking an (extreme?) “Keep it Simple” approach

  “We should grow the Web of Data, not build it” 16

17

Reflec<ons | Growing a Web of Data

1.  Linked Data can be simple and useful

2.  Using a common vocabulary should precede using a common grammar

3.  The Web is a two-‐way street, not a broadcast medium

4.  We shouldn’t try to build the Linked Data Web all at once or all ourselves.

  Introduce complexity through simple ini<a<ves that add immediate, mutual benefit

  Find your own role within the wider ecology
