Page Comparison

This feature allows you to further filter (narrow down) the results of a particular search, by selecting a specific value or a set of values for a given attribute in WSO2 G-Reg Store. You can provide the filtering criteria for multiple attributes.

You can configure this in the RXT of the asset type. For an example, you can enable categorization by adding new fields to a new Categorization table of SOAP Services as explained below.

Once you configure the RXT to enable categorization, you can select the categorization values for a particular asset in the WSO2 G-Reg Publisher when creating a SOAP Service using the G-Reg Publisher or updating a SOAP Service as shown below.

You can use categorization to search for a SOAP Service in the G-Reg Store by its category as shown below.
