  1. EMu Online Data Sources Brad Lickman For Taxonomy and Geolocation (and Vocabulary Control)

  2. Online Data Sources • Basically, any data discoverable via the Internet. • For example: • UNdata – 60 million data sets showing economic development country by country • National Statistical Agencies – Demographic information • Online museum collections searches • Essentially, these are web interfaces that allow searching on various data sets.

  3. Applicable Online Data Sources • Museum specific data sources exist, and are available online: • Taxonomy • Integrated Taxonomic Information System • World Register of Marine Species • Catalogue of life • Geolocation • Google Maps • GeoNames • GEOLocate • Vocabulary Control • Getty vocabularies (AAT, ULAN, TGN, CONA)

  4. Applicable Online Data Sources • These various resources are helpful to expand our research and cataloguing data and knowledge, validate and verify our data, and to establish standards by which we record these data.

  5. How do we use these in EMu? Manually…somewhat? Typically, a snapshot of the data source is loaded onto the EMu server.

  6. Load a snapshot of data. • KE can load various thesauri into the Thesaurus module

  7. Load a snapshot of data. • KE can load various thesauri into the Thesaurus module

  8. Load a snapshot of data. • KE can load the ITIS dataset into the Taxonomy module

  9. Load a snapshot of data. • KE could load the Gazetteer module with…something. • I’m not aware of this happening very frequently. • Does anyone even use the Gazetteer module?

  10. Load a snapshot of data. • Problems: • Scripts to load the data must be maintained and updated as new data sets are released. • Just a snapshot. • How do we get updates? • How do we know if our snapshot is out of date? • Time consuming process to re-load the entire data set. • What happens to records that reference old terms/names? • No one uses the Gazetteer module?

  11. EMu 3.1.01 Resources Tool The most common use of Resources is to extract data from the current record, insert it into a formatted url and launch a browser.

  12. Resources Tool - ULAN

  13. Resources Tool - ITIS

  14. Resources Tool – Google Maps

  15. Resources Tool – Georeferencing

  16. Resources Tool. A step in the right direction. We can now take advantage of online data sets using a more stream-lined method. Integration achieved by populating URLs with record terms.

  17. Resources Tool No two-way communication – bringing data from online data sources back into a record is done by hand (copy/paste at best). Resources tool can be tricky to configure – not everyone has the resources to use Resources.

  18. Use of Open Data By consulting online data sources, we can present results within the EMu client, pull selected data back, and use the results to enhance EMu records.

  19. Use of Open Data • Example: GEOLocate • Web application • Batch processing (csv) • Web services (JSON, SOAP)

  20. GEOLocate Web Application

  21. Use of Open Data • Example: Getty Thesauri • Linked Open Data • URIs point to terms, concepts, relationship, scope notes, etc.

  22. Use of Open Data

  23. Use of Open Data • Advantages: • No more copy/paste – more seamless integration • No configuration of EMu Registry to use Resources • We can be notified of changes – the process of updating is easier • Take advantage of collaborative work

  24. Use of APIs • Disadvantages: • Connection to all online resources must be maintained in-house • If connection protocols change, museums must keep up

  25. Use of APIs • Possible solution: • A KE server can manage all connections to various online data sources • Client sites simply contact KE server with the same requests

  26. Use of APIs

  27. Use of APIs • Advantages: • KE manages all connections. If/when the communication protocols changes, there is no impact on clients.

  28. Questions/discussion • Would the ability to seamlessly consult online data sources from within the EMu client improve how we use it? How?

  29. Questions/discussion • Which online data sources are we interested in?

  30. Questions/discussion • How do we want to use these data sources? ie. Should they be used as a reference, or be the ultimate authority?

  31. Questions/discussion • Should updates be automatically trusted?
