Retrieving Properties of a Published Query

Although I2E Queries and Multi Queries are binary objects, the I2E Web Services API provides an interface to a subset of the properties of those items, including some that can be modified when running a query programmatically.

Query properties that are read-only and that can be retrieved using the API include title, creator, comments and column headers. Query properties that can be modified before query submissions include number of hits, time limit and smart query parameters.

I2E has two, related, query resources: Saved Queries (that represent the binary files on disk, stored in the Repository) and Published Queries (that represent the Published location of the Saved Queries). To ensure that Users have permissions to see Query Properties, it is recommended that you only expose access to Published Queries.

Retrieving (by GET) a Published Query provides a “handle” to the Saved Query:

HTTP Header = X-Version: *, Accept: application/json
Success 200

The response should look something like:

“shared”: true,
“valid”: true,
“handle”: “/api;type=saved_query/4.1/Query1.i2q”,
“error”: null,
“editable”: true

If you then retrieve that handle, you will receive an error because the server is trying to represent the query itself as JSON

HTTP Header = X-Version: *, Accept: application/json
Error 406

Note that if you do want to retrieve the query itself (rather than its properties) then change the format that you Accept to “application/octet-stream”:

HTTP Header = X-Version: *, Accept: application/octet-stream
Success 200

To get the query properties in a readable format, ask for the properties attribute of the saved query:

HTTP Header = X-Version: *, Accept: application/json
Success 200

The start of the Query Properties should look something like this:

“smartQueryProperties”: {
“summary”: “This is a query summary”,
“creationDate”: “2013-10-04 21:01:17”,
“title”: “Query title”,
“privateComments”: “”,
“useInSmartQuery”: true,
“approxQueryTime”: “”,
“comments”: “Here are the query comments. These will be seen by users in I2E Express and I2E Pro”,
“creator”: “pbm”

One Response to Retrieving Properties of a Published Query

  1. […] GET the handle of type=published_index to find type=index. Note that this is similar to how to get the Saved Query type from Published Query type outlined in a previous post. […]
