Taxonomy and ‘lite’ data model for PPDM

Public Petroleum Data Model Association enhances spatial spec and moots taxonomy initiative.

Two projects from the Calgary-based Public Petroleum Data Model Association are taking shape - PPDM ‘Lite’ and an embryonic taxonomy initiative. PPDM Lite—supported by PetroCanada, Anadarko, Nexen and ESRI—has just released its first simplified, spatially-enabled data model for wells. The Lite data model also supports PPDM’s latest metadata schema. Test population of the Lite data model from PPDM V3.7 is a straightforward, rapid process. The Lite data model is currently being extended to seismic data.


PPDM is inviting interested organizations to sign up for its new Taxonomy and Meta Data (TMD) initiative. TMD sets out to provide support for text-based, unstructured information within the PPDM data model. The initiative will leverage work done on XML-based information exchange by the World Wide Web Consortium (W3C).


PPDM believes that integration of structured, unstructured and semi-structured information is critical to the efficient work processes that are mandated by the 2002 Sarbanes-Oxley act.
