User keywords, or 'tags', are words added to object records by other users to enhance their discovery. You can add keywords that may be useful in helping others find this object.

We are experimenting with tagging because sometimes museums describe objects in language that is highly specialist and user added keywords are useful in bridging the 'semantic gap' between the language of the museum and that of the user.

Any keywords listed have been added by other users like yourself. You can click on them to use them as search terms to dicover other objects. User tags
Related subjects lists the broad themes that have relevance to the object you are viewing. You can click these themes to see other objects related thematically. Related Subjects

'Autogenerated tags' are a new feature that we are testing. These tags are generated by passing the object record through the OpenCalais service from Reuters. This service makes a 'best guess' at the names, places, companies and specialist terminolgy that is in the text of the object records.

By clicking on a tag you can find all other collection records related to that person, place or company.

Because the tags are autogenerated there are likely to be some errors. If you spot one of these then please flag the tag for deletion by clicking the 'x'. Auto-generated tags: [Beta]

The Registration Number of an object is a unique identifying number applied by the museum at the point of acquisition. Current numbering format comprises the year of acquisition, followed by a sequential number. For example, '2007/45' is the Registration Number that represents the 45th acquisition in the year 2007. Registration number
