  1. MCD Status Report Trevor Watson 4 February 2008

  2. MCD Status Report Some facts and figures about the main MCD processes : • loading of new documents from 2006 (IPC8 Frontfile) • loading of IPC data for pre-2006 documents (IPC8 Backfile) • IPC Revision

  3. How much IPC data is there in the MCD ?

  4. % documents loaded in MCD with valid IPC8 (by pub date)

  5. Frontfile errors and warnings for documents published in November 2007

  6. MCD backfile history (pre-2006 documents) 2005 - IPC8 derived from ECLA, IPC 1-7 (and incrementally in 2006, 2007) 2006 - AU, DE, JP, EAPO, LT, PT, SI, US 2007 - DE, MD, RO, RU 2008 - BR, CZ, (KR), UA

  7. Sources of backfile data Sources of advanced family-level symbols - January 2008 Overall level of completeness (by document) around 91%

  8. Backfile completeness • overall figure of 91% can only be a rough guide • aspects of completeness • date • kind codes • technical area • quality (the difficult one !) • suggestion : • each NO to produce a standard 'Statement of MCD Completeness' for their own collection

  9. MCD revision life-cycle

  10. Revision periods - docs that arrived after first WLS - docs where new symbols not added

  11. Revision in practice • revision periods overlap more than expected • MCD solution : weekly / monthly procedures • termination of revision period not clearly defined

  12. Sources of IPC8 data • EPOQUE and esp@cenet • regular DocDB bibliographic data products • quarterly IPC8 incremental DVDs • revision results files (yet to be released)
