When you click the Schema tab under Databases, you will get the Manage Search Schema page. This page lists the available Search Schema attributes. The schema determines what information is in a resource description and what form that information is in. You can add new attributes or fields to an RD and set which ones can be edited and which ones can be indexed. When importing new RDs, you can convert schemas embedded in new RDs into your own schema.
The table below lists the Search Schema attributes and their description.

When you import new RDs, you can convert schemas embedded in new RDs into your own schema. You would use this conversion when there are discrepancies between the names used for fields in the import database schema and the schema used for RDs in your database. An example would be if you imported RDs that used Writer as a field for the author and you used Author in your RDs as the field for the author. The conversion would be Writer to Author, so you would enter Writer in this text box. |
Editable |
false |
If true (checked), the selected attribute (field) appears as Editable attribute in the Edit page for a resource description. Description, Keywords, Title and ReadACL are editable. |
Indexable |
true |
If true (checked), the selected attribute (field) can be used as a basis for indexing. Author, Title and URL appear in the menu in the Advanced Search screen for the end user. This allows end users to search for values in those particular fields. Author, Expires, Keywords, Last Modified, Title, URL and ReadACL can be used as the basis for indexing. |
