Standards stuff …

Deep-Time Digital Earth standard. Exxon/Open Group release O-PAS Version 2.0. 5G-ACIA ally on wireless IIoT/5G synergies. ISO updates Dublin Core metadata standard. OGC on CRS API candidate standard. Canada’s spatial data infrastructure. OMG’s AI Platform Task Force. OPC Foundation’s O-PAS certification. OPC UA Functional Safety R 1.00. EPSG upgrades CRS registry. New PIDX PriceSheet XSD schema.

The first Deep-Time Digital Earth (DDE) standards task group face-to-face meeting was held in Beijing earlier this year. DDE is to harmonize global deep-time digital earth data and share global geoscience knowledge. Tim Duffy from the OneGeology organization is advising on standards-based informatics and interoperable standards in geoscience.

The Open Group has just released O-PAS Version 2.0, Part 1 – a technical architecture overview, the first of 13 planned subsections of the ExxonMobil-backed process control standard. The document describes OCF, the O-PAS connectivity framework, a royalty-free specification for secure and interoperable communications, to be released in the upcoming Part 4. The OCF is conceptually a single network but will be implemented as separate, segmented networks to assure security and quality of service. Version 2.0 defines a ‘system of control systems and applications created and maintained by external management services’. A future version of the standard is to address platform-independent applications and the physical hardware layer. ExxonMobil has contracted with Yokogawa to run a new OPA Test Bed Collaboration Center in The Woodlands, Texas.

The Industrial Internet Consortium and the 5G Alliance for connected industries and automation (5G-ACIA) are to cooperate on interoperability, prevent fragmentation and maximize synergies of 5G for the Industrial Internet. The collaboration will address wireless connectivity and digital transformation across industries. More from the release.

ISO has announced an update of the international standard for descriptive metadata. ISO 15836-2, also known as the Dublin Core metadata element set Part 2 adds 40 new metadata properties to improve the precision and expressiveness of Dublin Core descriptions. ISO 15836-2 was developed by the ISO/TC 46 technical committee.

The Open Geospatial Consortium seeks public comment on the OGC API - Features - Part 2: Coordinate Reference Systems candidate standard. OGC API - Features provides allows for the creation, modification and query of geographic features on the web. The new standard is consistent with the OGC/W3C spatial data on the web best practices.

OGC and Natural Resources Canada are requesting input to the proposed revamp of Canada’s spatial data infrastructure (SDI). OGC is seeking suggestions for open APIs, machine learning, data lakes, the cloud and … blockchains!

The OMG’s AI Platform Task Force held its first meeting in September 2019 chaired by Claude Baudoin (cébé IT). The task force has set up a Wiki open to OMG members and non-members. The aim is for the OMG to be ‘the place to come for AI technology standardization’.

The OPC Foundation has been ‘aggressively’ working on its OPC UA certification program, helping vendors verify and certify applications. OPC expects the certification tool to be of use in the ExxonMobil/The Open Group’s O-PAS standard (above) of which OPC UA is a ‘key part’. OPC has it that O-PAS ‘will require 100% certification of all compliant products’. The Compliance Test Tool is available for both windows and Linux and includes PLCopen test scripts.

The OPC UA Safety working group has published Release 1.00 of its specification for interoperable communications functional safety, OPC UA Safety. OPC UA Safety comes under the auspices of the Field Level Communication (FLC) initiative.

The EU Petroleum Survey Group (EPSG), the geodetics arm of IOGP is in the process of upgrading the EPSG online registry and support web site to align with the revised ISO 19111:2019 data model. A beta EPSG repository for evaluation and testing is available and for API access. The new platform is expected to become the master EPSG registry mid-year 2020. More from the IOGP blog.

PIDX International has revised its PriceSheet XSD schema. Originally published in 2014, the 2020 edition is available royalty-free. The new schema allows for specific part information parameters to be exchanged between trading partners, ‘improving the efficiency and data accuracy of exchanging price books between suppliers and operators’ according to Margret Saniel of OFS Portal and chair of the price sheet project.
