Enterprise Metadata Discovery interfaces and implementation
for technology adapters
Version 1.1 of Enterprise Metadata Discovery includes enhancements for
configurable data handlers, function selectors, and data bindings, and a way to
build service descriptions using these configured artifacts and existing schemas.
The enhancements to Enterprise Metadata Discovery are useful when building
technology-style adapters that transform unstructured data to structured data and
make use of existing schemas instead of generating them from an EIS system.
Enterprise Metadata Discovery and technology-style adapters use data handlers,
function selectors and data bindings in the following ways:
v A data handler, which is a Java class or library of classes, is used by a process to
v A function selector is used by adapters performing inbound processing. The
v A data binding, which is a Java class, converts a stream of native data to a
(TwineBallMetadataSelection.MAXRECORDS);
new FunctionDescription[functionDescriptions.size()];
(CLASSNAME,SETFUNCTIONDESCRIPTIONS);
transform data into and from specific formats. In the WebSphere business
integration environment, data handlers transform text data of specified formats
into business objects, and transform business objects into text data of specified
formats.
function selector directs the data to the appropriate function in the
message-driven bean (MDB) or EIS export. A function selector may inspect data
or metadata to determine how and where to direct the data.
business object during inbound processing, and converts a business object to a
stream of native data during outbound processing.
