Request url: https://api.archivesportaleurope.net/services/search/eac-cpf. This service is a POST-request.

This search-service delivers a list of authority records for Corporate Bodies, Persons or Families (CPF) with the requested searchterm. A web developer is able to filter results on various facets.



Request parameters

Three request parameters can be used to do a search in descriptions of records creators and two types of filters can be used.

Empty Request example:

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

Basic Request example:

{
  "count": "5",
  "startIndex": 0,
  "query": "Onderwijsraad",
  "filters": [
    {
      "facetFieldName": "country",
      "facetFieldIds": [
        "7"
      ]
    }
  ],
  "dateFilters": [
    {
      "dateFieldName": "fromdate",
      "dateFieldId": "1800-01-01_2"
    }
  ],
  "sortRequest": {
    "sortType": "asc",
    "fields": [
      "string"
    ]
  }
}

This example searches for archival descriptions with the term "Onderwijsraad" and filters on the facet "country" with id = 7 (identifier for "NETHERLANDS") and date-facet "fromDate" with id = "1800-01-01_2" (identifier for the period 1800-1999).

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 searchterm(s). Required.

filters

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

dateFilters

Request parameters "dateFilters" enables you to filter the result on a certain period of time. The dateFacets are summarized in SearchEac#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 <existDates>

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.
