The fields marked (RF) describe the NXQL format that will search through all elements of that repeatable field. To limit the search to the primary value then append /0 to the field name, e.g. collectionobjects_mmi:mmiTechniques/0

Likewise, fields marked (RG) describe repeatable groups of fields. The underlying fields are shown with a wildcard in the field path to indicate that such an search term is required for the NXQL query string to return without a syntax error. The wildcard can be replaced with a 0 to indicate the primary value of that field should be only be searched upon.

The fields marked (CL) describe a field that is a controlled list (HTML select element). The returned value is a non-spaced string. Please see Controlled List mapping for a mapping of controlled list strings to displayed values.

(date) indicates a PostgreSQL "timestamp without time zone" type field and requires a DATE or TIMESTAMP literal in the NXQL notation. For instance, in non-URL encoded form:
collectionobjects_common:measuredPartGroupList//dimensionSubGroupList//valueDate <= DATE '2012-01-09' or
collectionobjects_common:measuredPartGroupList//dimensionSubGroupList//valueDate <= TIMESTAMP '2012-01-09T00:00:00'
See also Common Services REST API documentation and NXQL documentation.

(integer) indicates a field integer type.

(URN) indicates a field that uses a refname structure to indicate value and metadata for that field. See also refname.

Searching through a range of values using text based fields

The following is not the preferred form. Please see searching scalar values below.

NXQL supports the BETWEEN operator to search through a range of numerical or text values.

An example

http://cspacetest.collectionspace.org:8180/cspace-services/collectionobjects?as=collectionobjects_common/physicalDescription BETWEEN 'g' AND 'h'

Another example for a simple range of displayDate values for 1950's

http://cspacetest.collectionspace.org:8180/cspace-services/collectionobjects?as=collectionobjects_common/objectProductionDateGroupList/*/dateDisplayDate BETWEEN '%1950%' AND '%1959%'

BETWEEN doesn't give expected results when the displayDate value is in any format other than strictly numerical. Values like "stamped 1934", "Jan 1973, Feb 1973", "ca. 1922", "Feb-May, Dec 1975" and "February, 1934" are not found when bounding the BETWEEN operator between two numerical values.

Searching through a range of scalar date values for a structured date field

The structured date field type is a group of related fields which give greater definition of a date, range and certainty.

Searching through a range of dates for a structured date requires using the dateEarliestScalarValue and dateLatestScalarValue scalar fields of the structured date group.
These fields contain a postgres TIMESTAMP value in the form of YYYY-MM-DDThh:mm:ss where T is an indicator of a timestamp, e.g. 2012-03-27T11:23:00. the API will also accept queries using a DATE literal and internally convert to/from TIMESTAMP.

All scalar dates are saved in postgres with a lower bound time stamp, dateEarliestScalarValue, of T00:00:00 and a higher bound time stamp, dateLatestScalarValue, of T23:59:59.
An important fact about scalar dates in this context is that CollectionSpace modifies the saved postgres timestamp value by the server's timezone. This means the postgres scalar values are effectively 5 hours behind (NYC being UTC -5, ignoring DST) in CollectionSpace. This impacts the way in which DATE or TIMESTAMP ranges are calculated using the REST API.

For example, say there is a search for all dates from 1954.
Using the DATE literal, rather than search from a lower bound of 1954-01-01 and a higher bound of 1954-12-31, there would be a recalculated search from 1953-12-31 up through 1955-01-01.
Using the TIMESTAMP literal, the range search would take into consideration the server timezone (non DST value) and recalculate based on that value. The updated query would have a range from 1953-12-31T19:00:00 up through 1954-12-31:19:00:00.

REST API query payload columns returned

The following columns are returned from an API query call to the collectionobject service

briefDescriptions is used for the browser search results listing page. The related thumbnail image requires a separate call to the relationship service. (See section below for additional details.)

Get referenced authority records

Append authorityrefs to the API URL for a collectionobject record to get a list of referenced authority records': sourceField, itemDisplayName and refName (in short ID format).

An example API call for authorityrefs for a given collectionobject record

http://cspacetest.collectionspace.org:8180/cspace-services/collectionobjects/a7fdba4a-ec23-472c-9c45-47249aa3242d/authorityrefs

Finding related media records from a given collectionobject record

The relations service provides the mechanism to find related records of a given type. With a known collectionobject csid the API call would be

http://cspacetest.collectionspace.org:8180/cspace-services/relations?sbj={{csid}}&objType=MediaTenant42

The objType value is the document type for the unique MMI tenant, MediaTenant42.
