Best Practices

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

Link multiple representations
Implement 303 redirects for
real-world objects

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