Analyze Schemas with the XML Schema Infoset Model

s the use of schemas grows, so does the need for tools to manipulate those schemas. IBM's new XML Schema Infoset Model provides a complete modeling of schemas themselves, including the concrete representations as well as the abstract relationships within a schema or set of schemas. This library easily queries the model of a schema for detailed information. You can also use it to update the schema to fix any problems found and write the schema back out.

Although there are a number of parsers and tools that use schemas to validate or analyze XML documents, tools that allow querying and advanced manipulation of schema documents themselves are still being built. The XML Schema Infoset Model (AKA the Java packages org.eclipse.xsd.*, or just "the library") provides a rich API library that models schemas—both their concrete representations (perhaps in a schema.xsd file) and the abstract concepts in a schema as defined by the specification. As anyone who has read the schema specs knows, they are quite detailed. The XML Schema Infoset Model strives to expose all the Infoset details within any schema. This allows you to efficiently manage your schema collection, and empower higher-level schema tools such as schema-aware parsers and transformers.
