- <h2>Sample SGML Open Entity Catalog for HTML
-
- <p>The SGML standard describes an "entity manager" as the portion or
- component of an SGML system that maps SGML entities into the actual
- storage model (e.g., the file system). The standard itself does not
- define a particular mapping methodology or notation.
-
- <p>To assist the interoperability among various SGML tools and
- systems, the SGML Open consortium has passed a technical resolution
- that defines a format for an application- independent entity catalog
- that maps external identifiers and/or entity names to file names.
-
- <p>Each entry in the catalog associates a storage object identifier
- (such as a file name) with information about the external entity that
- appears in the SGML document. In addition to entries that associate
- public identifiers, a catalog entry can associate an entity name with
- a storage object identifier. For example, the following are possible
- catalog entries:
-
- <listing>
- &catalog;
- </listing>
