PODS, the Pipeline open data standards association has released Version 7.0 of its pipeline data model for comments. Speaking at the 2019 PODS user conference, Chad Corcoran (Andeavor) and Pete Veenstra (Pivvot) presented the new 7.0 major release along with PODS Lite, a free subset of the PODS 7.0 model. PODS 7.0 represents a simplification of the data model that no longer mandates linear referencing for feature location and provides a formal data exchange specification.
PODS 7 leverages the ‘next generation’ PODS initiative, a modern approach to database design and deployment. A single PODS 7.0 conceptual model is delivered in Sparx Enterprise Architect, describing business concepts, entities and relationships. The conceptual model is used to derive a logical model, an agnostic framework for documenting and extending the model. Finally a physical model can be implemented in a database platform of choice (a specific RDBMS or geographic information system such as an Esri geodatabase). The approach allows both PODS 7.0 and PODS Lite to interoperate with, for instance, Esri’s ArcGIS Pro pipeline reference model.
The comprehensive model includes a rigorous treatment of units of measure and business rules such that, for instance, a UOM can be applied to specific routes (such as USA/Canada cross-border issues) or for various descriptions of pipe coating thickness. Business rules contain information on how records are managed when a feature location is moved or altered. PODS 7.0 and PODS Lite due for final release in August with business rule and data exchange documentation to follow in Q3 2019. More from PODS.
