About the External Content editor

Commands to save, save and close, and close the External Content editor.

URL or URI that specifies the location of external media using a standard format.

A warning message appears if the external content is located on the local computer hosting System Platform.

A media type is a two-part identifier that specifies the type of application required to process or view remote content. A media type can be entered in the field or selected from a drop-down list.

A warning message appears if a media type is specified that does not have an associated viewer application.

Content type assigned to the external media that enables ViewApp algorithms to place content in specific panes during runtime.

Reference

If you select Reset from the drop-down menu, any value entered in the field is discarded, and the type reverts to Constant with a default value of "about:blank."

Name of the External Content item.

Drop-down list with options to browse for an external content file or specify a URL using HTTP or HTTPs.

When URI/URL is set to Reference or Expression, the drop-down list changes to the Galaxy Browser icon (...), and you can use it to select references.

Open validates the location of external media specified in the URL or URI field, if a Constant value has been selected for the field. An attempt is made to display the external media in an application assigned as the default by the operating system, not the app specified for the external content media type.

The Open button is disabled if a Reference or Expression has been selected.

A warning message appears if the content cannot be found at the location specified in the URL or URI field.

Suggest is optional. When selected, it automatically selects a media type based on the entry in the URL or URI field, if a Constant value has been selected for the field. The entered value can be changed if the suggestion does not match the expected media type.

The Suggest button is disabled if a Reference or Expression has been selected.

Note: Ensure the suggested media type is correct. The external media does not appear if the media type is incorrect.
