510 field in People authorities does not have $i or $4

[ahankinson]

The 500 field allows for a $i value to determine what the relationship is between a person and another person, but the corresponding 510 for people to corporate bodies does not allow $i, so the type of relationships cannot be specified.

There should also be a corresponding controlled list of the possible values, which could be selected from the list of RDA Agent relationships:

http://www.rdaregistry.info/Elements/a/

In this case the appropriate RDA URI could also be inserted in $4.

Further notes:

The 678 field contains additional information about a particular institutional relationship. However, since the two fields are not directly connected, and only refer to each other with their sigla, this is not ideal:

1. We cannot (easily) construct the link to give more information about the relationship information between the two fields, since the siglum is not contained in the authority record -- we would have to retrieve the pointed-to record, extract the siglum, and then try to match it against a free value in the 678$a;
2. Not all institutions have a siglum;
3. The relationship descriptions are in the cataloguing language, so cannot easily be translated to other languages.

[ahankinson]

Another observation for this issue: 700 and 710 use the $4 field in the same way as the authorities use the $i field. We should probably standardize this behaviour across sources and authorities.

And publications, as well?

Regarding 678: We've (+ Alexander) revised the guidelines for this field in the meantime and our recommendation is merge it with 680 and delete it. This is a leftover from Kallisto that doesn't work any more, and it is obsolete to us.
