PODS Lite Executive Summary Introduction Since 1998, the Pipeline Open Data Standard (PODS) Association has been focused on providing a comprehensive, open, vendor-neutral, highly scalable, and proven enterprise database architecture focused on increasing the safety and integrity of pipelines worldwide. The PODS Association announces the release of PODS Lite, an abbreviated version of the full PODS Pipeline Data Model allowing pipeline industry professionals to explore how implementation of this recognized and established data model may improve their pipeline data management, integrity and risk management, operational and regulatory reporting activities. Pipeline operators and other interested parties not yet using the full PODS Pipeline Data Model, along with Association members not yet familiar with the PODS data standards, are encouraged to use PODS Lite to evaluate the PODS Pipeline Data Model capabilities and value. For existing Association members and users of the full PODS Pipeline Data Model, PODS Lite provides an opportunity to preview the Associations Next Generation Data Model. The PODS Association is offering the PODS Lite Data Model free of charge to anyone wishing to evaluate and understand how the PODS Pipeline Data Model can support their needs.
PAGE 2 What Is PODS Lite? PODS Lite is a subset of the full PODS Pipeline Data Model including many of the core tables of the full Data Model. The specific list of core tables provided with PODS Lite is described in more detail below. The PODS Association is currently developing a new PODS Data Model Version 7.0. This new version will be a transformational not an incremental change from the current Data Model Version 6.0. This transformation of the PODS Data Model is being conducted under the PODS Association s Next Generation initiative. As such, PODS Lite also operates as a preview of the new PODS Pipeline Data Model Version 7.0, being developed as part of the PODS Next Generation initiative. This release of PODS Lite is being made available in the Esri geodatabase format. This version, referred to as PODS Lite Geodatabase for APR, will work with Esri s ArcGIS for Pipeline Referencing, or APR, extension. This is possible because the Esri APR linear referencing extension will work with any data model that meets certain requirements; the PODS Pipeline Data Model Version 7.0 and PODS Lite meet these requirements. The PODS Association and Esri have worked collaboratively on the development of PODS Lite for APR. PODS Lite allows pipeline operators to take advantage of both Esri s APR and the PODS Pipeline Data Model. Pipeline operators will realize significant value when using APR s linear referencing and data management tools along with the PODS Lite Data Model. PODS Lite Overview Free for Use by All PODS Lite is available to both PODS Association members and nonmembers. Both are encouraged to use PODS Lite to understand how the PODS Pipeline Data Model works and what value it provides. Subset of the Full Data Model PODS Lite is a subset of the full PODS Pipeline Data Model. A set of core tables is provided, allowing users to preview the PODS Core linear referencing, asset and operational tables. Preview of PODS Version 7.0 PODS Lite is a preview of PODS Pipeline Data Model Version 7.0, scheduled for initial release in 2017 and full release in 2018. Preview of Modernized PODS Standards PODS Lite reflects a major re-design and modernization of the PODS Pipeline Data Standard taking place as part of PODS Next Generation initiative. Available for Multiple Platforms While PODS Lite is being made available initially in Esri geodatabase format for use in Esri s ArcGIS for Pipeline Referencing (APR) extension, PODS Lite will also be available for other GIS and RDBMS platforms in early 2017. PODS Lite, though, is not specific to Esri or the Esri APR extension to the ArcGIS Platform. The next rollout of PODS Lite will support implementation in additional relational database management system (RDBMS) and geographic information system (GIS) environments, scheduled for release in early 2017. PODS Next Generation The PODS Association s Next Generation, or Next Gen, initiative is focused on a complete re-design and modernization of the PODS Pipeline Data Model. The re-design of the PODS Pipeline Data Model is driven by PODS Association Strategy objectives as defined in its 2016-2019 Strategic Plan, as well as from nearly 20 years of PODS Pipeline Data Model implementation experience and lessons learned. The Next Gen initiative will result in a new data model the PODS Pipeline Data Model Version 7.0 as well as a Data Exchange Specification and migration and implementation guidance and instructions. The Next Gen Data Exchange Specification will facilitate data translations between the PODS Pipeline Data Model Versions 7.0 and earlier as well as other data models and will also enable system integration via service-oriented approaches. The re-designed Data Model will standardize and modernize data management and reporting across the pipeline industry.
PAGE 3 The Next Gen initiative is scheduled for completion in 2018. The PODS Association will be providing incremental releases of the full PODS Pipeline Data Model starting in 2017 with the release of Version 7.0. As a subset of Version 7.0, PODS Lite offers current and potential future Association members the opportunity to preview the redesigned data model. More information on the Next Gen initiative and outcomes can be found on the PODS web site at https://www.pods.org/nextgeneration/ PODS Next Generation Design Principles Design for the Future The next PODS Pipeline Data Model will be transformational not an incremental update to the existing standard. A Solid Core Coupled with Agility and Flexibility The Data Model will allow for independent extension of the model in a flexible fashion yet in alignment with core modeling and design principles. Support Time and History The Data Model will support time-based events and track asset lifecycle history. Support Location and Spatial Representation The Data Model will provide flexibility to include or exclude spatial representation of assets and events. Support Interoperability The Data Model will support data exchanges between systems and work streams within an organization as well as data exchanges between organizations. Easy to Understand The Data Model will be easy to understand, implement, extend and use. What s included in PODS Lite? As a subset of the PODS Pipeline Data Model Version 7.0, PODS Lite provides a data model allowing users to collect and manage data for: Pipeline Hierarchy Defining the pipelines in a system and how they are organized, as well as the ability to define sites and stations and where they are located in space. Linear Referencing Enabling referencing of assets, events and conditions along a pipeline via measures and/or stationing. Linear referencing tables provided in PODS Lite include centerline, centerline sequence, continuous measure network, engineering stationing network and calibration points. It is these tables that enable use of Esri ArcGIS for Pipeline Referencing (APR) extension and toolset. Use of linear referencing tables (and APR) is optional when using PODS Lite. Should users elect to not use the PODS Lite linear referencing tables, location can be collected and managed via XYZ coordinate positions. Assets Installed and in-service product transport or containment devices, when connected end-toend form a pipeline in the ground. Assets may be located by a measured position along a pipeline or alternately by an XYZ coordinate position. A subset of assets provided in PODS Lite includes pipe segments, coatings, valves, pipe bends, girth welds and pigging launchers and receivers. Conditions Representing the state or condition of a pipeline and representing the results of activities including inspection or analysis (population class study, high consequence area analysis). A subset of condition and operational tables provided in PODS Lite includes inspection range, class, operating pressure (to manage maximum allowable operating pressure or MAOP and maximum operating pressure or MOP), test pressure, consequence segment, pipeline operating condition, pipe jurisdiction and crossings including online, pipeline, utility, hydrology and transportation.

PODS Association Overview Since 1998, the PODS Pipeline Data Model has been increasing safety and integrity of pipelines worldwide by providing pipeline operators with an enterprise database architecture that is comprehensive, open, vendorneutral, highly-scalable, and proven. PODS supports the growing and changing needs of the pipeline industry through ongoing development and maintenance of its Pipeline Data Model and standards. This work is led by the PODS Technical Committee on Governance, responsible for the strategic technical direction of PODS Association. The work, including debate, deliberation and resulting recommendations, is conducted through the assigned Project Teams and Work Groups. PODS lowers the risk, cost, and time required to implement a pipeline GIS. Maintaining a single pipeline data repository helps pipeline operators to improve the quality, quantity and timeliness of pipeline information managed. PODS is an open standard, so members can choose software applications based on features, cost and usability. Multiple vendors may develop software products that interact with the PODS database. Pipeline operators don t have to be tied to a single vendor s proprietary data model. PODS promotes better business processes and workflow. Members will experience reduced data transfer between software applications and multiple databases; clear, concise definitions; plus, the ability to clearly delineate data ownership. PODS Association membership leverages a broad knowledge-base. As a PODS Association member, organizations immediately become part of a global network of over 170 companies, associations and agencies to access a wealth of technical knowledge and experience from other PODS members. Members work collaboratively to develop and refine the PODS Pipeline Data Model.
