ISA is undertaking a number of initiatives to promote interoperability in Europe

European Interoperability Framework

Catalogue of interoperability assets

Google not good enoughThere are too many websitesI don’t know what to use

Is it the right version?Is it machine-readable?

ASSET DESCRIPTION METADATA SCHEMA

ADMS

1. Raise visibility of reusable specifications

2. Simple way to find interoperability assets from different publishers

3. Add valuable metadata to these specifications

How does it look like?

Core Vocabularies

Pilots using Linked Data technologies

Core vocabulariesSimplified, reusable, extensible and model neutral data models that capture the fundamental characteristics of a data entity in a context-neutral fashion.

Best Practices

http://education.data.gov.uk/doc/schools/123456.csv

e.g. http://education.data.gov.uk/doc/school?id=123456

e.g. http://education.data.gov.uk/doc/school/v01/123456

e.g. http://education.data.gov.uk/ministryofeducation/id/school/123456

Follow the pattern

Re-use existing identifiers

Link multiple representations

Implement 303 redirects for real-world objects

Use a dedicated service

Avoid stating ownership

Avoid version numbers

Avoid using auto-increment

Avoid query strings

10 rulesfor persistent

Avoid file extensions

e.g. http://{domain}/{type}/{concept}/{reference}

e.g. http://education.data.gov.uk/id/school/123456

e.g. http://data.example.org/doc/foo/bar.htmle.g. http://data.example.org/doc/foo/bar.rdf

i.e. independent of the data originator

e.g. data.gov.uk and publications.europa.eu are decoupled from specific government department and could readily be transferred and

run by someone else if necessary.

e.g. http://education.data.gov.uk/id/school1/123456e.g. http://education.data.gov.uk/id/school1/123457
