XML Catalogs
The XML catalog mechanism enables files to be retrieved from local folders, thus increasing the overall processing speed, as well as improving the portability of documents—since only the catalog file URIs then need to be changed. See the section How Catalogs Work for details.
Altova's XML products use a catalog mechanism to quickly access and load commonly used files, such as DTDs and XML Schemas. This catalog mechanism can be customized and extended by the user, and it is described in the sections Catalog Structure in RaptorXML Server and Customizing your Catalogs. The section Variables for System Locations list Windows variables for common system locations. These variables can be used in catalog files to locate commonly used folders.
This section is organized into the following sub-sections:
•Catalog Structure in RaptorXML Server
•Variables for Windows System Locations
For more information on catalogs, see the XML Catalogs specification.
Installing schemas via Schema Manager
Schema Manager enables you to quickly and conveniently install important schemas and set up catalog files to correctly access these installed schemas. See the Schema Manager section for more information.
If a document is validated against a schema that is not installed but is available via Schema Manager, then the installation via Schema Manager will be triggered automatically. However, if the schema package to be installed via Schema Manager contains namespace mappings, then there will be no automatic installation; in this case, you must start Schema Manager, select the package/s you want to install, and run the installation. If, after installation, RaptorXML Server is not able to correctly locate a schema component, then restart RaptorXML Server and try again.
