Thursday, February 23rd, 2023OGC seeks Public Comment on v3.0 of GeoXACML and related JSON Profile
Tuesday, February 21st, 2023
Request Open: February 21, 2023 12:00 am — March 23, 2023 12:00 am (29 days left)
The Open Geospatial Consortium (OGC) seeks public comment on version 3.0 of the OGC Geospatial eXtensible Access Control Markup Language (GeoXACML) Standard and its related JSON Profile (v1.0). Comments are due by March 23, 2023.
The OGC Geospatial eXtensible Access Control Markup Language (GeoXACML) 3.0 Standard is a geospatial extension to the OASIS eXtensible Access Control Markup Language (XACML) v3.0 standard, which defines a common language for expressing security policy. As per the XACML documentation, “If implemented throughout an enterprise, a common policy language allows the enterprise to manage the enforcement of all the elements of its security policy in all the components of its information systems.”
GeoXACML 3.0 extends XACML 3.0 to support the interoperable definition of access rights that include geographic conditions, providing additional spatial constraints for XACML-based security policies.

STAplus brings features to improve the usefulness of the SensorThings API to Citizen Science.
Monday, February 20th, 2023The Open Geospatial Consortium (OGC) is seeking public comment on STAplus 1.0. STAplus is an extension to the OGC SensorThings API Part 1: Sensing Version 1.1 (STA) Standard data model that is based on requirements from the Citizen Science community. Comments are due by March 23, 2023.
STAplus (SensorThings API extension PLUS) defines a SensorThings data model extension that improves FAIR data principles when exchanging sensor data by including licensing and ownership information.
The dominant use for the OGC SensorThings API (STA) data model (and API) can be thought of as “a single authority provides sensor readings to consumers.” However, in Citizen Science there are many contributors (citizens) whose observations together form the “big picture.”
The STAplus extension is designed to support a model in which observations are owned by (different) users that may express a license for re-use.
OGC to create Agriculture Information Model Standards Working Group; Public Comment Sought on Draft Charter
Friday, February 3rd, 2023New SWG will develop an Agriculture Information Model that will provide a common language for agriculture applications to harmonize and improve data and metadata exchange.
The Open Geospatial Consortium (OGC) is looking to create an Agriculture Information Model Standards Working Group (AIM SWG). Public comment is sought on its draft charter. Comments are due by February 23, 2023.
The purpose of the AIM SWG is to develop, publish and maintain an Agriculture Information Model (AIM) to support interoperability of information in the Agriculture Domain, with emphasis on the re-use of generic OGC standards as appropriate.
AIM will provide a common language for agriculture applications to harmonize and improve data and metadata exchange by defining the required data elements, including concepts, properties, and relationships relevant to agriculture applications, as well as their associated semantics/meaning for information exchange.
OGC to form GeoDCAT Standards Working Group; Public Comment sought on Draft Charter
Wednesday, February 1st, 2023The GeoDCAT SWG aims to separate a general geospatial profile of DCAT, called GeoDCAT, out from the Europe-specific Application Profile, GeoDCAT-AP.
The Open Geospatial Consortium (OGC) is in the process of forming a new GeoDCAT Standards Working Group (SWG). Public comment is sought on its draft charter. Comments are due by February 22, 2023.
The purpose of the SWG is to revise, publish, and maintain GeoDCAT – a spatio-temporal profile of the W3C DCAT Recommendation – and provide guidance about its use and further specialization. The larger geospatial community will benefit from the standardization of descriptions of geospatial data and access services in DCAT-based data catalogs.
DCAT, a vocabulary to describe datasets and services, is the primary means to catalog datasets on the web. Some basic temporal and geographic properties have been adopted within DCAT v2 and planned v3, however these do not address the full range of requirements as identified in the 2019 OGC GeoDCAT-AP Discussion paper.
OGC seeks Public Comment on FlatGeobuf becoming a Community Standard
Friday, February 10th, 2023FlatGeobuf is a performant binary encoding for geographic data that works well as a “cloud native” lossless format for vector data.
The Open Geospatial Consortium (OGC) is looking to adopt FlatGeobuf as an official OGC Community Standard. Comments are due by March 13, 2023.
FlatGeobuf is a performant binary encoding for geographic data that can hold a collection of Simple Features. Because of its simple core design and efficient I/O handling, FlatGeobuf can work well as a “cloud native” lossless format for vector data. FlatGeobuf is based on flatbuffers.
FlatGeobuf was designed to be: suitable for storing and accessing large volumes of static data; significantly faster than legacy formats; unconstrained by size limitations for contents or metainformation, and; suitable for streaming/random access. No other current format combines good performance and “cloud native” design.
