Tag always return no data

[olivi...@forthi.com]

Hi,

I'm currently using the following API to make the request,

http://api.digitalnz.org/v3/records.json?api_key={0}&text={1}

but the response getting for the "tag" count is always zero, any idea where can I get the exact information for the tag value.

Thanks for any reply.

Cheers,

Olivia

Hi Olivia,

The 'tag' field is normally only used for behind the scenes DigitalNZ purposes to help with the harvesting process or grouping collections. I don't think it will contain much content related metadata, but if it does it should show up naturally with your API call. You can confirm this by adding "&and[tag]=CEISMIC" to your API call to see some records that do have that field populated.

http://api.digitalnz.org/v3/records.json?api_key={0}&text={1}&and[tag]=CEISMIC

There is a more general 'subject' field that might be more what you are after. To see that you currently need to add "&fields=verbose,subject" to your API call, and then a "&and[subject]=policy" can be used to narrow in on some records that have metadata in that field.

http://api.digitalnz.org/v3/records.json?api_key={0}&text={1}&and[subject]=policy&fields=verbose,subject

Hope that helps, let me know if you have any more questions.

Thanks

Dan
