Request url: https://api.archivesportaleurope.net/services//hierarchy/ead/{id}/children. This service is a POST-request.

This hierarchy-service delivers a list of all archival descriptions one level deeper in the hierarchy of the archival description identified with {id}. A web developer can use this service to create a tree-like presentation of a finding aid, holdings guide or source guide.



Request parameters

Two request parameters can be used to get a list of children of an archival description.

Empty Request example

ID = .....

{
  "count": "5",
  "startIndex": 0
}

Basic Request example

ID = C376209320

{
  "count": "5",
  "startIndex": 0
}

On [base_url]/search/ead/C376209320/children, it gives all the clevel descriptive units one level deeper in the hierarchy of the descriptive unit identified with "C376209320".

N.B.: you can find the (internal APE) identifier of a descriptive unit (always starting with a "C") which is necessary for using this service via the /search/ead service

count

The resultlist is delivered in chunks of a certain size. Request parameter "count" describes the number of results that are in one chunk. Optional. Default value is 5.

startIndex

Request parameter "startIndex" enables you to select the results that you want to have. Counting starts at zero. If "count" = 5, the second chunk starts with startIndex 5, the following at startIndex 10, etc. Optional. Default value is 0.

Response parameters

The response contains a list of the descriptive units where the requested search term(s) was/were found.
