Standards stuff

IOGP Seabed Survey guidelines. CAPE-OPEN interop installers. RTI’s DDS-based industrial internet. ISO/IEC 80000 Part 13 IT definitions for quantities and units.

The International association of oil and gas producers, IOGP, has just issued Reports 462-01, Guidelines for the use of, and 462-02, Guidelines for the delivery of, its Seabed Survey Data Model (SSDM). The reports emanate from the IOGP’s Geomatics Committee and concern the SSDM V2.0 release. The new data model is delivered as a UML template in Enterprise Architect for both ArcGIS implementation and GML encoding.

The interoperability special interest group of the downstream Colan standards body has released a developer guide for installers of V2.0 CAPE-OPEN type libraries and primary interop assemblies (PIA). The .NET PIAs target process simulation software developers implementing the CAPE-OPEN interoperability standards. PIAs ensure consistent installation, registration and removal of older software on an end-user’s machine. The document explains the requirements governing what the installers need to do, the technologies used to develop the installers and how they should be used by software vendors delivering CAPE-OPEN compliant software.

A ‘second version’ (a.k.a V1.8!) of IIRA, the Industrial internet consortium’s reference architecture has just been published. The new IIRA includes ‘tweaks, updates and improvements,’ in particular a new ‘layered databus’ architectural pattern. The new pattern was contributed by Real-Time Innovations to accommodate companies that embed RTI’s DDS protocol. For the uninitiated, a databus is a ‘data-centric information-sharing technology that implements a virtual, global data space, where applications read and update data via a publish-subscribe communications mechanism.’ The RTI implementation adds ‘rules and quality of service parameters, such as data rate, reliability and security.’ RTI blogger Brett Murphy commented, ‘You can implement a databus with a lower level protocol like MQTT, but DDS adds higher-level QoS, data handling, and security.’

The ISO/IEC 80000 series of quantities and units standards is updating Part 13: information science and technology covering ‘names, symbols and definitions for quantities and units used in information science and technology.’
