VML Processing Widget

One day soon, this page will document the VML Processing Widget. This an ANT-scripted process that:

• consumes proposals for change expressed in the HL7 Vocabulary Maintenance Language (VML),

• splits these proposals into two source streams targeted at the Access repository in which the HL7 Vocabulary content is stored::
  • an SQL update stream for updating files of properties assigned to vocabulary objects, and

  • an XML sream processed in Java to update the primary Access tables

  together, these streams update the vocabulary content stored in the Access repository,

• uses a Java process to "clean up" the Access content,

• invokes RoseTree to express the complete vocabulary content in HL7 Model Interchange Format (MIF), and

• combines this MIF content from the Access repository with an externally maintained MiF extension file to arrive at a final, complete expression of HL7's vocabulary in MIF.
