    <dd>the set of results for the retrieval, typically with a structure of <code>{ items: [], paging: {} }</code>, though the paging portion may be missing if there are not multiple results to page through (i.e. when retrieving by RID).</dd>
  </dl>
  <h3>Details</h3>
  <p>
    This uses the both GET- and POST-based Information Governance Catalog REST APIs to retrieve
    metadata using the most efficient means possible.
  </p>
  <h4>Complex Query option</h4>
  <p>
    Using the Complex Query option, you can run an arbitrary search.  For example, you can pass a query like this:
  </p>
  <p>
    <code>
    {
      "properties": ["name"],
      "types": ["term"],
      "where":
      {
        "operator": "and",
        "conditions": [
          {
            "property": "modified_on",
            "operator": ">=",
            "value": "1483232400"
          }
        ]
      }
    }
    </code>
  </p>
  <p>
    to get a listing of the names of all business terms that were modified on
    or after January 1, 2017 (value provided as UNIX time).
  </p>
  <p>
    If Query is empty, will look for the query in <code>msg.query</code>.
  </p>
  <h4>URL Passthrough option</h4>
  <p>
    Using the URL Passthrough mode allows you to invoke any arbitrary GET-based Information Governance Catalog
    REST API URL.  For example, you can pass any URL returned by a previous query's <code>next</code> property
    (for pagination), or the <code>_url</code> property (to get more details on that particular asset).
  </p>
  <p>
    If URL is empty, will look for the URL in <code>msg.url</code>.
    (Note: if specific host details are supplied in the URL they will be overridden by the Server
    selected via configuration -- this is necessary to ensure credentials are passed appropriately).
  </p>
  <h4>RID option</h4>
  <p>
    Using the RID option you can retrieve a single asset's details by its unique Information Governance Catalog ID (RID).
    You can also (optionally) provide a list of specific properties to retrieve for the asset: in general this is a good
    practice, as it is more efficient than retrieving all properties.  Note that when doing so, specifying the type of the 
    asset then also becomes mandatory.
  </p>
  <p>
    If RID is empty, will look for the RID as a string in <code>msg.rid</code>; if Properties is empty, will look for
    properties as an array in <code>msg.properties</code>; if Type is empty will look for the type as a string in 
    <code>msg.type</code>.

  <p>Stores, updates or removes metadata from Information Governance Catalog.</p>
  <h3>Inputs</h3>
  <dl class="message-properties">
    <dt>rid <span class="property-type">string</span></dt>
    <dd> the unique ID (RID) of the IGC metadata asset to update or delete</dd>
    <dt class="optional">type <span class="property-type">string</span></dt>
    <dd> the type of asset to create, when the operation is Create</dd>
    <dt>details <span class="property-type">object</span></dt>
    <dd> the detailed set of properties to create or update against the metadata asset</dd>
  </dl>
  <h3>Outputs</h3>
  <dl class="message-properties">
    <dt>payload <span class="property-type">string | object</span></dt>
    <dd>results of successful operations: the RID (string) for Create, updated properties (object) for Update, and empty for Delete</dd>
  </dl>
  <h3>Details</h3>
  <p>
    This uses the appropriate Information Governance Catalog REST API to make updates to metadata, 
    whether creating new assets, updating existing assets, or deleting existing assets.  All operations
    will push their results out to the output port for optional consumption; if any error has occured, 
    an error will be thrown with the details -- use a Catch node to capture these.
  </p>
  <h4>Create operation</h4>
  <p>
    The Create operation should only be used when an asset does not already exist in IGC with the 
    details that need to be stored.  If the asset already exists, and you simply wish to set some 
    additional properties on the asset (or replace existing ones), use the Update operation instead.
    Using the Create operation, you need to provide both the Type of the asset to create and the Details
    of the property values to set within it.  Note that different assets have different required properties 
    as part of their creation; in general this will require at least the 'name' property.
  </p>
  <p>
    The standard output will be the RID of the created asset, as a string.
  </p>
  <p>
    For example, use a Type of 'category' and provide Details like this:
  </p>
  <p>
    <code>
    {
      "name": "Test Category"
    }
    </code>
  </p>
  <p>
    to create a new top-level category named 'Test Category'.
  </p>
  <p>
    If Type is empty, will look for the type as a string in <code>msg.type</code>; if Details is empty, 
    will look for the detailed properties as a JSON object in <code>msg.details</code>.
  </p>
  <h4>Update operation</h4>
  <p>
    The Update operation expects a unique IGC identifier ("RID") to specify which specific piece of metadata
    to update.  Details are also needed to define what on that piece of metadata should be updated.  This second 
    parameter is expected to be a JSON object, and should contain only the properties that need
    to change on the asset.
  </p>
  <p>
    The standard output will be the changed properties of the asset (typically matching the provided 
    Details), as a JSON object.
  </p>
  <p>
    For example, you can use the following Details:
  </p>
  <p>
    <code>
    {
      "short_description": "a new short description",
      "labels": {
        "items": [ "6662c0f2.22257cc4.p864keo17.vbbgrpe.26j4m1.mgcmn0lh4fb2ggdjb7ujo", "6662c0f2.22257cc4.p864keo18.0o97qi8.f1ar57.dmjlsjtjghbifmi6p2tc4" ],
        "mode": "add"
      }
    }
    </code>
  </p>
  <p>
    to update the short description of the piece of metadata, and also add (append) two new labels.  
    Note:
    <ul>
      <li>related items must also be specified by their RID</li>
      <li>using <code>replace</code> as the mode will overwrite any existing relationships (and if you provide an empty array, will remove all existing relationships).</li>
    </ul>
  </p>
  <p>
    If RID is empty, will look for the RID as a string in <code>msg.rid</code>; if Details is empty,
    will look for the detailed properties as a JSON object in <code>msg.details</code>.
  </p>
  <h4>Delete operation</h4>
  <p>
    Like the Update operation, the Delete operation requires a unique IGC identifier ("RID") to specify which 
    specific piece of metadata to delete.  No details object is needed as the entire asset (and all of its properties) will be deleted.
  </p>
  <p>
    On successful deletion, the standard output will be empty (just a payload containing only Node-RED's _msgid).
  </p>
  <p>
    If RID is empty, will look for the RID as a string in <code>msg.rid</code>.
  </p>
