Best Practices

14. Example
10 rules URIs for persistent
Follow the pattern Avoid stating ownership
e.g. http://{domain}/{type}/{concept}/{reference} e.g. http://education.data.gov.uk/ministryofeducation/id/school/123456
Re-use existing identifiers Avoid version numbers
e.g. http://education.data.gov.uk/id/school/123456 e.g. http://education.data.gov.uk/doc/school/v01/123456
Link multiple representations Avoid using auto-increment
e.g. http://data.example.org/doc/foo/bar.html e.g. http://education.data.gov.uk/id/school1/123456
e.g. http://data.example.org/doc/foo/bar.rdf e.g. http://education.data.gov.uk/id/school1/123457
Implement 303 redirects for Avoid query strings
real-world objects
e.g. http://education.data.gov.uk/doc/school?id=123456
Use a dedicated service Avoid file extensions
i.e. independent of the data originator http://education.data.gov.uk/doc/schools/123456.csv
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.
