Public Schedule

The OMG seeks your input on the open processes listed on this page. These may include Requests for Comments (RFC), Requests for Information (RFI), and Requests for Proposals (RFP). Any interested parties may respond to any of these. Below are the details of what responses we are seeking in each case and how to respond to these.

Requests for Comments (RFC)

RFCs are specifications that have been submitted to the OMG via the "Request for Comments" process, as being existing industry specifications or de facto standards for which the submitters are seeking formal standardization via the OMG's proven process. We seek feedback on whether these specifications are suitable for publication as formal international standards via the OMG.

The OMG aims to publish standards which are unique, timely and provide business value. Please let us know if you are aware of any potential issues regarding these specifications as currently proposed, for example if you are aware of other formal standards that cover the same scope. This is part of our due diligence process towards advancing these specifications to become formal international standards.

Anyone can respond to these requests for public comments, and may do so via the RFC Response Form.

Comments must be received by the Monday 4 weeks before the next OMG Quarterly Meeting. All public comments will be taken into account at the end of the current review period, before we progress with the "Finalization" process to adopt these as formal OMG specifications. Minor comments will be addressed during Finalization.

Requests for Information (RFI)

From time to time the OMG puts out a Request for Information (RFI) in order to seek industry input on potential future standardization efforts. Anyone may respond to these.

The intent of an RFI is to gather information for the purpose of guiding a subgroup in its efforts to provide solutions to industry problems. The RFI process is used by a subgroup to canvass a targeted industry segment for one or more of the following purposes:

  • Acquiring general or specific information about industry requirements.
  • Soliciting assistance in identifying potential technology sources.
  • Soliciting input to validate the roadmap of a subgroup.

Generally speaking, the RFI process determines which Request For Proposals (RFPs) will be issued (and, based on negative feedback, which won't) or influences the way a particular RFP is constructed.

You may respond to any RFI by downloading the RFI document, responding to the questions and returning your response to rfi-responses [at] omg.org

In addition, some RFIs are accompanied by an on-line survey link. These will contain the same questions as the published RFI document, and you may respond using either method at your convenience.

Requests for Proposals (RFP)

RFPs are requests from the OMG for proposed standards. Any interested party may register an interest in submitting a response to an RFP. To register your intent to respond to one of the open RFPs on this page, please submit a Letter of Intent to the OMG at loi [at] omg.org using the LoI Template. You do not need to be a member of the OMG to submit an LoI but you would later need to join at the appropriate membership type and level if you intend to follow up the LoI with a formal submission.

NOTE: original process dates are given within the RFP documents themselves but these may be extended by subsequent motions of the relevant Technical Committee. RFPs that are listed on this page remain open at this time.

Data Product Ontology RFC


The Data Product (DPROD) specification is a profile of the Data Catalog (DCAT) Vocabulary, designed to describe Data Products. This document defines the schema and provides examples of its use. DPROD extends DCAT to enable publishers to describe Data Products and data services in a decentralized way. By using a standard model and ontology, DPROD facilitates the consumption and aggregation of metadata from multiple Data Marketplaces. This approach increases the discoverability of products and services, supports decentralized data publishing, and enables federated search across multiple sites using a uniform query mechanism and structure.

Augmenting Data Sets with Semantics RFI
The Augmenting Data Sets with Semantics RFI is issued by the Financial Sector Domain Task Force (FSDTF). The goal of the FSDTF in issuing this RFI is to gather input concerning the challenges of augmenting data, particularly market, commercial and other critical financial data, with metadata providing semantics that assist with interpreting and reusing that data. The effort is motivated by financial sector use cases in which organizations that have either licensed or otherwise have access to business-critical data sets need additional information about those data sets for automated processing purposes. We are looking for respondents to comment on the usefulness, importance and parameters of a possible specification that could address the issues related to communicating the semantics of a dataset. The FSDTF expects that other industry sectors will benefit from the results of this RFI, but the focus at this time is on responses clarifying the needs of the financial sector. You may respond to this RFI by downloading the RFI document, responding to the questions and returning your response to rfi-responses [at] omg.org You may also respond via the on-line survey. The online survey contains the same questions as the published RFI document, and you may respond using either method at your convenience. The RFI response deadline is November 11, 2024.

The OMG is seeking your input on the open processes listed below. Please refer to the top of this page for what we are requesting and how to respond.


Agent Metamodel and Profile (AMP) RFP
This Request for Proposal solicits submissions for an Agent Metamodel and Profile (AMP). Essentially, the AMP RFP requests a metamodel and profile for extending UML with capabilities applicable to agents and agent-based software. Submissions developed in response to this RFP will achieve the following: Clarify semantics concerned with modeling agents. Establish Agent modeling best practices utilizing OMG technologies. Develop a MOF-compliant agent metamodel to be used either standalone or via extending the existing UML metamodel with agent modeling capabilities. Enable agent model interchange between tools via XMI. Optionally facilitate modeling of Peer-to-Peer, Grid and Cloud computing, and other technologies in terms of a collection of Agents. It is expected that responses to this RFP will make good use of agent modeling capabilities already supported by the OMG.


DDS C# API Request For Proposal
The Data Distribution Service (DDS) specification consists of a UML Platform-Independent Model (PIM) and a single IDL Platform-Specific Model (PSM). As a result, DDS implementations have traditionally implemented APIs that derive directly from the IDL PSM using the standard IDL to language transformations that are available for multiple programming languages. However, often times these IDL-derived mappings preclude programmers from using native programming language constructs, such as generics, that are unavailable in IDL. The result is a suboptimal API that does not conform to the stylistic idioms of the target language, introducing a barrier to the adoption and use of DDS. Since 2012, the OMG has released DDS PSMs that derive directly from the DDS UML PIM, targeting languages like C++ and Java. These new PSMs leverage and conform to the standard data types and programming idioms of such programming languages, simplifying the adoption and use of DDS. Following that evolution, this RFP solicits proposals for a DDS PSM for the C# programming language


DDS Status Monitoring RFP
The Data-Distribution Service (DDS) provides a crucial connectivity platform to many mission critical systems. It is important to have a standardized means for monitoring the health status of the DDS platform during live operation and to use means that are robust to failures of the platform being monitored. This standard covers the information model and technical interfaces required. This RFP solicits proposals for the following: A data model defining the information required for the operational status monitoring of a DDS platform. Techniques, procedures, and interfaces to communicate the data model representing the status of the platform.


Digital Receipt JSON Document RFP
This RFP solicits proposal for standard Digital Receipt document in JavaScript Object Notation (JSON) [JSON] format. In the past the Association for Retail Technology Standards (ARTS) released a few versions of the Digital Receipt standard XML schemas. The last version of the Digital Receipt 3.1.0 [DR-31] was released in 2017. The changes implemented in that schema were designed to accommodate the requirement of the Japanese market, so that the schema could be used to simplify the processing of POS transactions during the Olympics. Since version 2, the Digital Receipt XML schemas were based on a much larger and more complex POSLog XML schema [POSLOG]. However, in recent years, the shift from using XML format to JSON, especially in messaging and APIs, began to expose limitations of the current Digital Receipt XML standard. Furthermore, the ARTS Digital Receipt specification was primarily focused on the consumer facing aspects of receipt, as a document issued by a retailer to a customer confirming the details of a retail transaction. There is another important aspect of the transactional data. It is used by government agencies for fiscal audit and control of retail operations. Such fiscal receipts include other types of transactions such as tender control or financial transactions performed at a Point of Service (POS). For example, fiscal printers used the same transactional data to print customer receipts as well as to capture fiscal data for government reporting. This RFP solicits proposals for a standard Digital Receipt JSON document that can be used to produce both a consumer facing receipt as well as transactional data for governmental reporting. This RFP solicits proposals for the following: A structure of Digital Receipt JSON document expressed as JSON schema [JSON-S] or Open API Specification [OAS] Schema Objects using YAML syntax. A Retail Industry Ontology that covers the major concepts in the Digital Receipt JSON document.


Enterprise Resource Metadata Attributions (ERMA) Request For Proposal
This RFP focuses on the data requirements for defining a computing environment through the use of Enterprise Resource Metadata Attributions (ERMAs). ERMAs describe the information and data elements needed to provide risk-managed operations within any computing environment. A computing environment comprises, at a minimum: + Hardware: components and relationships (component tree). + Software: systems, applications and services operating on hardware components. + Network Interfaces: the physical communication between components. Optionally, the operational environment may use ERMAs to describe users and data in the operational environment. This RFP explicitly seeks the definitions, structure and vocabularies for the hardware, software and network ERMAs needed to operate a risk-managed computing environment. Optionally, this RFP seeks ERMAs for user and data elements in the computing environment.


Event Metamodel and Profile (EMP) RFP
This Request for Proposal solicits submissions for an Event Metamodel and Profile (EMP). Essentially, the EMP RFP requests a metamodel and profile for extending UML with capabilities applicable to the sensing and interpretation of events, such as monitoring, filtering, aggregation, and correlation. Submissions developed in response to this RFP will achieve the following:
  • Clarify semantics concerned with modeling events.
  • Establish Event modeling best practices utilizing OMG technologies.
  • Develop a MOF-compliant event metamodel to be used either standalone or via extending the existing UML metamodel with event modeling capabilities.
  • Enable event model interchange between tools via XMI.
It is expected that responses to this RFP will make good use of event modeling capabilities already supported by the OMG.


Ground Data Delivery Interface (GDDI) Request For Proposal
Space vehicle operations require varying compositions of ground applications that are integrated together within a common network (WAN and/or LAN) to provide an end-to-end ground system capability. This includes real time data and metadata transfer across these applications. Typical data includes spacecraft bus commands, telemetry, and mission payload in digital/baseband form. Metadata is carried in-band with the data and includes parameterized information and real-time status used by the ground applications to properly process, store, retrieve, and deliver the data. No common model for this dynamic data/metadata interface currently exists. Approaches, designs, and custom protocols vary widely from one vendor to another offering little opportunity for reuse to system integrators. The result is often a costly and time-consuming integration effort. This RFP solicits proposals for the following: * A Platform-Independent Model describing a lightweight application-level message interface that encapsulates spacecraft data and metadata so they can be transferred between ground applications within a common network. * At least one Platform-Specific Model describing the encoding format of the metadata and data encapsulated by this interface. This platform specific model will call out at least one standard transport layer for carrying the encapsulated/encoded metadata and data, with the intent of reusing an existing transport that provides high throughput, low latency, and optionally secure transmission.


Interface Definition Language v4 (IDL4) to Python Language Mapping RFP
Version 4 of the Interface Definition Language (IDL) specification extends the traditional IDL syntax and defines a comprehensive set of building blocks to categorize it. Such evolution of IDL requires the definition of a new set of language mappings, because existing mappings, such as IDL to Python, do not include complete coverage of the new constructs introduced in IDL version 4 and newer, and do not map well to the new building-block structure. This RFP solicits proposals for an IDL4 to Python mapping


Information Management Metamodel (IMM) RFP
This RFP solicits proposals for a standard metamodel to address the needs of Information Management. This includes the scope of the existing Common Warehouse Metamodel (CWM) standard but is extended to cover the following areas:
  • MOF2 Metamodel for Information Management (IMM)
  • UML2 Profile for Relational Data Modeling, with a mapping to the IMM metamodel and SQL DDL
  • UML2 Profile for Logical (Entity Relationship) Data Modeling, with a mapping to the IMM metamodel
  • UML2 Profile for XML Data Modeling, with a mapping to the IMM metamodel and XML Schema
  • UML2 Profile for Record Modeling, with a mapping to the IMM metamodel and COBOL Copybooks
  • A standardized Information Engineering data modeling notation with a mapping to the IMM metamodel



RTPS TCP/IP PSM for DDS Interop RFP
The DDS Real-time Publish-Subscribe wire protocol (DDSI-RTPS) specification uses a Model-Driven Architecture (MDA) to describe a Platform Independent Model (PIM) of the interoperability wire protocol and its Platform Specific Mapping (PSM) to the User Datagram Protocol (UDP). The existing standard specifies only a UDP mapping of the PIM that allows conforming implementations to interoperate over UDP. The objective of this RFP is to define a standard PSM to the Transmission Control Protocol (TCP), so that implementations conforming to this specification can interoperate over TCP. Responses to this proposal shall not modify or deprecate UDP-based interoperability or the RTPS PIM.


Robotic Interaction Service Framework 2.0 RFP
This RFP solicits proposals for the following as well as RoIS 1.2 Specification: -Common interfaces between robotic service applications and components that provide functions for performing human-robot interaction. -Data structure for each interface. This RFP also solicits proposals for the following extension to RoIS 1.2 specification: -Semantic definition of requirements and functions of each component using Robotic Service Ontology (RoSO). -Isolation of communication model (infrastructure) of robotic functional components.


Semantic Information Modeling for Federation (SIMF) RFP
The SIMF RFP asks for submissions for a standard that addresses the federation of information across different representations, levels of abstraction, communities, organizations, viewpoints, and authorities. Federation, in this context, means using independently conceived information sets together for purposes beyond those for which the individual information sets were originally defined. The purpose of SIMF is to help federate information across different authorities, vocabularies and formats. Current conceptual and logical information modeling approaches tend to be focused on a particular information modeling problem, using a particular technical approach. Examples of such technical approaches include object modeling, DBMS modeling and exchange schema modeling. SIMF seeks to address the problem of information federation by specifying standards for conceptual domain modeling, logical information modeling and model bridging relationships. SIMF submissions will define, adopt and/or adapt languages to express the conceptual domain models, logical information models and model bridging relationships needed to achieve this federation. Many if not all of these capabilities can be achieved with expert application of multiple standards and technologies. SIMF is intended to unify and tailor these capabilities, providing a standard for tools that reduce the barrier to entry and overhead required to achieve federated information.


SBRM RFP
This RFP solicits a specification that complements established mechanisms for representation of structured data files submitted as business reports, typically financial reports to regulators, in formats such as XBRL, by - Applying a business modeling approach to report definition, making reports easier to develop; - Enabling business-level expression of rules in order to manage quality; - Facilitating reuse of information across multiple reports; - Allowing use with industry- or enterprise-standard information models and ontologies; - Allowing direct linkage with enterprise information sources for report data; - Providing alternative formats for reports to allow access by a greater variety of analytical tooling while providing interoperability with XBRL-based report definitions and report submissions.


Statistics Metadata Interoperability RFP
There are many governmental agencies, university centers, and private companies around the world producing statistical datasets. These datasets cover a broad spectrum of subjects with a wide variety of detail. Due to their different sources, conventions, levels of description, and styles, it is hard to discover what datasets exist, and to understand their suitability for, a given task. This RFP solicits proposals for standard metadata to accompany statistical datasets for the purposes of discovery and understandability.


UnifiedPOS Fiscal API 2.0 RFP
This RFP solicits proposals for the following: A platform independent behavioral model to describe interactions between fiscal devices or services and applications that consume them. A standard Fiscal API to register retail transactions on a fiscal device or tax authority service. A standard Fiscal API to store data into a fiscal journal


UnifiedPOS V2 Model And POS Printer API RFP
This RFP solicits proposals for the following: A platform independent behavioural model to describe interactions between device services and applications that consume them. The new model should address the shortcomings of the UnifiedPOS V1 and provide a foundation for exposing devices as services. An API to query POS printer capabilities. An API to print information on paper rolls using receipt and journal stations of the POS printer. An API to print information on a form (typically a check or credit card slip) on the slip station of the POS printer.
