Use cei:idno@id for atom:id if existing

Created by: icarus-eu

To enable the use of an atom:id that is different from the charters' signature at import-time, the cei:idno@id attribute should be used as identifier for the database.

Current status:

The cei:idno@id attribute is currently completely ignored in the import process. For example, the following elements

  • <cei:idno>DL_4231</cei:idno>
  • <idno id="004401">DL_4231</idno>
  • <cei:idno id="DL_4231">DL_4231</cei:idno>

are all transformed to <cei:idno id="DL_4231">DL_4231</cei:idno> during the import process.

Suggested functionality:

  1. On import, every charter is checked for an existing cei:idno@id attribute. If it is present, the content is used as the identifier in the database
  2. If the attribute is missing, the content of the cei:idno element is used for this purpose, in addition of it functioning as "signature" of the charter (visible in the charter view).

Problems:

  • Is there currently a check whether or not the used data is unique inside the current fond / collection? If not, should this check exist?
  • Is the cei:idno@id attribute used in some other function than solely as database identifier of the document?

Example:
