Open Social Semantic Web Platform for Academic Resources
Providing platforms for Linked Open Data
Practicing data accumulation and publishing
Interested Areas

Geographical information, especially geographical names
Local information

3. Museum data as LOD
The state-of-the-art of museum information in Japan
Distributed
Self maintained
Isolated
Opaque
Self designed
Messy
Aggregating and associating museum information
LODAC-Museum
4. Linked Open Data
Publish data as re-useable
Not PDF or excel
Use RDF (Resource Description Framework)
Web of Data
Linked Data Principle by Tim Berners-Lee
Use URIs as names for things
Use HTTP URIs so that people can look up those names.
When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL)
Include links to other URIs. so that they can discover more things.

Keep it flat as long as possible
Metadata elements
Work:46
Person:23

10. Integration Policy
How to integrate data from different sources
sharing of responsibility
Each source is responsible for its data
Identifying IDs for data and managing data with the IDs
LODAC is only responsible for integration
Assigning original IDs and associating other IDs to them
Data from Source B
