There are a number of extra properties we want to store in a resource:

• resource size (in bytes, no. triples etc.) - ​https://trac.dataco.coi.gov.uk/projects/datagov/ticket/673
• resource hash is 'static' (default) or 'changeable' - ​https://trac.dataco.coi.gov.uk/projects/datagov/ticket/674
• alternative link (e.g. TNA Web Archive) to use the link is broken - ​https://trac.dataco.coi.gov.uk/projects/datagov/ticket/173

i.e. this is a much needed enhancement

Need to be able to read/write these values in web interface and API.

(At some point we may wish to have custom form widgets for these new fields in the resource table, but let's leave this for the future.)

Implementation

I suggest these are arbitrary key/value pairs, just like package extras, reusing PackageExtra? code as much as possible. (Other much more radical alternative is to move model to RDF.)

Documentation article on caching / improving performance. (To complement configuration docs.)

• Different sorts of cache - beaker style, etags, package_dict in search results(?)
• How each one affects performance
• How to turn them on/off and configure them
• Is it possible to bypass each of them in the browser or with wget/curl?
