Appendices

There are a number of appendices that deal with the syntax required for various query parameters and payload formats.

The Query Syntax appendix describes the JSON based query language used to query records in EMu tables. It covers all aspects of searching including all the available operators and how those operators map into EMu. A query is performed by setting the filter query parameter.

The Sort Syntax appendix covers the format required for the sort query parameter used to collate records matching a query.

The Patch Syntax appendix details JSON Patch which is used to apply edit operations on an existing record. The PATCH method on an EMu resource allows records to be updated.

The Select Syntax appendix outlines the format of the select query parameter, used to restrict the columns returned from a search.

The HTTP Method Override describes how GET requests with very long URLs, so long they exceed limits, can be transmitted via a POST request.
