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

This search-service delivers a list of archival descriptions with the requested search term in the subtree of the archival description identified with {id}. A web developer can use this service to create a tree-like presentation of a search result.

Request parameters

Three request parameters can be used to do a search in archival descriptions.

Empty Request example

ID = .....

{
  "count": "5",
  "startIndex": 0,
  "query": "*",
  "filters": [
    {
      "facetFieldName": "string",
      "facetFieldIds": [
        "string"
      ]
    }
  ],
  "dateFilters": [
    {
      "dateFieldName": "string",
      "dateFieldId": "string"
    }
  ],
  "sortRequest": {
    "sortType": "asc",
    "fields": [
      "string"
    ]
  }
}

Basic Request example

ID = F1045936

{
  "count": "5",
  "startIndex": 0,
  "query": "nepal",
  "filters": [
    {
      "facetFieldName": "string",
      "facetFieldIds": [
        "string"
      ]
    }
  ],
  "dateFilters": [
    {
      "dateFieldName": "string",
      "dateFieldId": "string"
    }
  ],
  "sortRequest": {
    "sortType": "asc",
    "fields": [
      "string"
    ]
  }
}

On [base_url]/search/ead/F1045936/descendants, it gives all the clevel descriptive units of the finding aid identified with "F1045936", that contain the search term "nepal".

N.B.: you can find the (internal APE) identifier of a finding aid (always starting with a "F") 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.

query

Containing the search term(s). Required.

filters

Request parameter "filters" enables you to filter the result on facets. The facets are summarised in searchEadDescendants#facets.

dateFilters

Request parameters "dateFilters" enables you to filter the result on a certain period of time. The dateFacets are summarised in searchEadDescendants#date_facets

sortRequest

Request parameters "sortRequest" enables you to sort the result. The sortRequest contains two parameters: sortType and fields.

In "fields", you can provide a list of 1 or more fields. The resultlist is ordered on field[0] first, field[1] secondly, etc. The possible fields are:

date: date of the archival material, provided in <unitdate>
findingAidNo: number of the finding aid, provided by the repository in <eadid>
title: description of the archival material, provided in <unittitle>
referenceCode: identifier of the archival material, provided by the repository in <unitid>

In all situations you can sort ascending or descending by setting request parameter "sortType" "asc" or "desc" respectively.

Response parameters

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

totalResults

The response parameter "totalResults" gives the number of results.

startIndex

The response parameter "startIndex" gives the number of the chunk you requested.

totalPages

The response parameter "totalPages" gives the number of chunks.

eadSearchResults

Enumeration of the results. A result could be a holdings guide, a source guide, a finding aid, or a descriptive unit (ie a sublevel component). They are all optional except "id".

id	Internal APE identifier of the result
findingAidTitle	Title of the finding aid
findingAidNo	Identifier of the fonds provided by the repository
repository	Name of the repository holding the fonds
country	Name of the country where the repository is, in English
language	Language of the description of the result
langMaterial	Language in which the result is created
unitDate	Date of creation of the result.
repositoryCode	Code of the repository holding the fonds; preferably, but not necessarily ISIL
hasDigitalObject	TRUE/FALSE
numberOfDigitalObjects	Amount of digital objects available for the search result (is always 0 in case 'hasDigitalObject' = FALSE)
numberOfDigitalOjectsInDescendents	Amount of digital objects available for descendents of the search result (can be > 0 in case 'hasDigtalObject' = FALSE)
numberOfDescendents	Amount of descendents of the search result
docType	Type of archives describing document where the result is found: "Finding Aid", "Holdings Guide", "Source Guide" or "Descriptive Unit"
docTypeId	Acronym for the type of archives document: "fa" for "Finding Aid", "hg" for "Holdings Guide", "sg" for "Source Guide" or "du" for "Descriptive unit"
level	Type of result: "archdesc" for highest level description or "clevel" for subordinate components
indexDate	Date showing when the result was ingested/updated and indexed in the Archives Portal Europe (ie last change date)
unitId	Identifier of the result provided by the repository
parentId	Internal APE Identifier of the parent of the result
unitTitle	Description of the result
unitTitleWithHighlighting	Description of the result, with the mark "<em>" to emphasise the search term that was used in the search request
scopeContent	More descriptive information about the result.
scopeContentWithHighlighting	More descriptive information about the result, with the mark "<em>" to emphasise the search term that was used in the search request
numberOfAncestors	Amount of ancestors (higher levels) for the result

sortFields

This response parameter sums up the various fields you can use to order the resultList in a, new, additional request (see: searchEadDescendants#sortRequest):

date
findingAidNo
orderId
title
referenceCode

facetFields

This response parameter gives an enumeration of facets. Every facet has three variables.

id	Internal APE identifier of the value; use this "id" in the filter request parameter
name	Human readable value (in English)
frequency	The number of results of this facet containing the search term

facets

country	Name of the country where the repository is, in English
subject	Subject that is added to the archival description
repository	Name of the repository holding the fonds
docType	Type of document in which the result is found: "Finding Aid", "Holdings Guide", "Source Guide" or "Descriptive Unit"
level	Type of result: "archdesc" for highest level description or "clevel" for subordinate components
hasDigitalObject	TRUE/FALSE
digitalObjectType	Type of the Object: most of the time: IMAGE
unitDateType	Type of date describing the archival unit

date facets

With the date facets you can zoom in on the period of time. Results are grouped in periods of two centuries in the first step. If you use these groupings in the request-parameter dateFilter, you'll have new dateFacets that groups the results into groups of two decades

fromDate	Grouping of the search result in starting dates
toDate	Grouping of the search result in ending dates
