3. What is the DM Workbench ? Reference implementation load the Data Migration subpack contents (and all 3 terminologies and 2 classifications too) Full Working Prototype author queries in one terminology translate to another terminology fake/import SNOMED instance data analyse, repair, xmap, query, report.. tokenised search with word equivalents

4. Under the hood… Software ‘stack’ GUI for most functions Command Line Interface with scripting Terminology services API Zero install MS Access under OGL (WinXP/Win7 Access 2003,2007,2010,2013) Data Load One-button import of TRUD data (WHO data for ICD10) Common information model Range of query and instance data formats
