OraCIF TRANSFORMER is under development and this stage is currently incorporated into the Exporter.

At the moment the Exporter produces fully formatted mmCIF or XML documents. However, in order to get greater control over the formatting of the output, these two steps are being decoupled and the Transformer will allow the data extracted from the source database(s) to be more readily reformatted into a wide range of formats.

The Transformer uses XSL Stylesheets to reformat XML documents into mmCIF, XML, HTML and other mark-up languages. OraCIF Transformer uses the facilities provided by Oracle XML DB which follow W3C's recommendations.

INPUT

The Transformer requires Xml document(s) and XSL stylesheet(s). The stylesheet(s) can either be taken from an internal OraCIF repository or else can be supplied as an input parameter. The Xml document(s) can be given as a single CLOB or as a Selector job identifier from which the XML documents were generated using the Exporter. This is useful when is necessary to apply the same stylesheet to a set of Xml documents and they are stored within OraCIF tables.

PROCESS

For each pair (XML document, XSL stylesheet) the Transformer invokes the Oracle XML DB function to make the corresponding transformation.

OUTPUT

The transformed document(s) is returned as a CLOB and can be stored in a OraCIF table.
