Terms & Acronyms

Object Management Group Terms and Acronyms

This glossary collects most of the terms and acronyms that you'll encounter at OMG meetings, and in OMG documents. Each definition is only as authoritative as its cited source; this document itself is not an official reference. Technical terms are defined in our official specifications, and procedural terms are defined in our Policies and Procedures document. If our explanation here goes beyond what appears in these documents, it is our attempt to clarify and not to impose our interpretation on a topic. References are collected at the end of this document.

Terms in italics, and virtually all acronyms, have their own entry in the list. You may have to convert an italicized term to singular form to find it - for example, proxies is represented by the entry Proxy.

PIM: See Platform-Independent Model
Platform: (NOTE: OMG members are still discussing the definition of Platform; this is not the only definition under consideration.) A set of subsystems and technologies that provide a coherent set of functionality through interfaces and specified usage patterns, which any application supported by that platform can use without concern for the details of how the functionality provided by the platform is implemented [MDA Guide].
Platform Independence; Platform-Independent Model (PIM): A model of a subsystem that contains no information specific to the platform or the technology that is used to realize it. The quality that the model is independent of the features of a platform of any particular type. Like most qualities, platform independence is a matter of degree. A view of a system from the platform independent viewpoint. A PIM exhibits a specified degree of platform independence so as to be suitable for use with a number of different platforms of similar type. [MDA Guide]. 
Platform Independent Viewpoint: Focuses on the operation of a system while hiding the details necessary for a particular platform. A platform independent view shows that part of the complete specification that does not change from one platform to another [MDA Guide].  
Platform-Specific Model: A model of a subsystem that includes information about the specific technology that is used in the realization of it on a specific platform, and hence possibly contains elements that are specific to the platform. A view of a system from the platform specific viewpoint, combining the specifications in the PIM with the details that specify how that system uses a particular type of platform [MDA Guide].
Platform-Specific Viewpoint: Combines the platform independent viewpoint with an additional focus on the detail of the use of a specific platform by a system [MDA Guide].  
Platform Member: OMG membership category which may submit technology to, and votes in, PTC but not DTC; votes in all SIGs, TFs, and SCs; and is eligible for a seat on OMG's BoD.

Proposed Specification: Synonym for Submission. Also see Technology Adoption Process.
Proxy: (1) Voting rights in an OMG subgroup, transferred to a person who does not work for a Member, by a written directive signed by a Member's Registered Voter: "I hold a proxy for Company X and vote in favor of the motion." (2) A written directive to a subgroup or plenary chair, or to OMG staff, to cast a specific vote (for, against, or abstain) on a particular motion, or group of motions, at a particular meeting. A proxy directing a vote of abstain on all issues at a particular meeting brings that meeting closer to quorum without affecting the direction of decisions on issues that come before the meeting. (3) Proxy Holder: The individual named in writing by an OMG Member's (that is, a company's) Registered Voter to vote in place of the Registered Voter in OMG plenary bodies. The designation may be permanent until revoked ("Standing Proxy"), or for a single meeting. The term may also be used to describe any person who holds a proxy to vote at a meeting of any OMG subgroup. NOTE 1: Proxies must be signed by the Member's registered voter and submitted in writing before they may be exercised. FAX submittal is acceptable, but email is not. At the last minute during a meeting, proxies may be FAXed directly to the meeting hotel, to the attention of a suitable OMG staff person or directly to the person who will exercise the proxy, if not an OMG staffer. Responsibility for delivery of the proxy rests with the member company, and not with OMG. NOTE 2: The OMG Policies and Procedures (P&P) document contains the official definition of, and prescribes the use of, proxies at OMG meetings. This definition may be more helpful and easier to understand, but only the P&P definition is official.

SOAP: Simple Object Access Protocol
SoC: System on a Chip
Software Assurance AB Special Interest Group: OMG subgroup with the primary mission of working with other OMG subgroups  and other software industry entities and groups external to the OMG, to coordinate the establishment of a common framework for analysis and exchange of information related to software trustworthiness.
Software-Based Communications (SBC) Domain Task Force: OMG subgroup focusing on software-based communications including software-based communication devices. OMG specifications supporting JTRS are defined here.
SOPES: Shared Operational Picture Exchange Services
Space DTF:
OMG subgroup focusing on software for space satellite and ground systems.  
Special Interest Group (SIG): One of the three types of OMG Subgroups, a SIG may be chartered by any one of the three Plenary Bodies. Unlike TFs, SIGs may not recommend issuance of RFPs or adoption of technology to their Parent Body, nor may they issue RFIs although they may issue Surveys which serve the same function as an RFI but carry a different name. Typically, SIGs function as discussion groups. Occasionally a SIG will be disbanded and its Parent Body will charter a TF with similar name and function, typically after a period of several months to a year or more during which the SIG demonstrated that its membership could sustain the effort necessary to recommend and maintain adopted technology. 
Special Interest Group Chair: A Member Representative elected by the SIG, responsible for leading the activities of that SIG, and reporting these activities of the SIG to its Parent Body.
SPEM: Software Process Engineering Metamodel, an OMG RFP.  
SPMS: Structured Patterns Metamodel Standard (ex-IPMSS)
Standing Proxy: see Proxy.
STIX: Structured Threat Information eXpression. STIX™ is a collaborative community-driven effort to define and develop a standardized language to represent structured cyber threat information.
STV: See Single Transferable Vote.
SysA: System Assurance
SysEng:  Systems Engineering. 
SysML™: Systems Modeling Language
System: The MDA Guide presents MDA concepts in terms of some existing or planned system. That system may include anything: a program, a single computer system, some combination of parts of different systems, a federation of systems, each under separate control, people, an enterprise, a federation of enterprises… Much of the [MDA] discussion focuses on software within the system [MDA Guide]. 
Systems Engineering Domain Special Interest Group: OMG subgroup supporting the evolution of model based systems engineering standards to achieve the following goals: providing a standard systems modeling language to specify, design, and verify complex systems; facilitating the integration of systems and software engineering disciplines; and promoting rigor in the transfer of information between disciplines and tools for developing systems.
Subcommittee (SC): One of three types of OMG Subgroups, a SC may be chartered by any one of the three Plenary Bodies. Subcommittees typically deal with organizational issues; current SCs include the Liaison Subcommittee, the Policies and Procedures Subcommittee, and the Object and Reference Model Subcommittee. Only Contributing, Platform, and Domain Members may vote in Subcommittees. 
Subgroup: An OMG body chartered by a Plenary Body. There are three types of Subgroups, each defined separately in this glossary: Task Force (TF), Subcommittee (SC), and Special Interest Group (SIG). An OMG Member (that is, a company) represented in a subgroup has a single vote in motions before that subgroup, regardless of how many representatives (that is, employees of that member company) happen to attend a particular meeting.
Submission: Synonym for Proposed Specification. A document submitted in response to an RFP. Also see Technology Adoption Process, Initial Submission and Revised Submission.



TacSIT: Tactical-Situation Display
Task Force: The OMG Technology Committee subgroup responsible for issuing a RFP and evaluating submission(s)
TFC: Task Force Chair.
: See Technology Committee.
Technology Adoption Process: Defined by the P&P, the Technology Adoption Process has a number of steps. Check the definitions of italicized terms for details not repeated here. (1) Optionally, a TF may issue an RFI. The information gathered via an RFI may be used to generate zero, one, or more RFPs. (2) The TF writes an RFP and votes to recommend that its Parent Body issue it. (3) The AB certifies that the RFP is consistent with MDA and with all previously adopted OMG technology. (4) The Parent Body votes, which formally issues the RFP. (5) On or before the deadline specified in the RFP, submitting companies respond with LOIs. Submitting companies must be either Contributing Members (for any RFP), or Platform Members (for RFPs issued by the PTC), or Domain Members (for RFPs issued by the DTC). (6) On or before the next deadline, submitting companies submit Initial Submissions which are presented to the TF at one of its regularly scheduled meetings. (7) On or before the next deadline, submitting companies submit Revised Submissions which are presented to the TF at one of its regularly scheduled meetings. The Revised Submission deadline may be extended, and this step repeated, one or several times. (8) The TF evaluates the technology described in the submissions and, typically, recommends one to its Parent Body for adoption. (9) The AB certifies that the technology complies with the MDA and is consistent with previously adopted OMG technology. (10) The TF's parent TC votes by email or FAX to recommend adoption of the technology to the BoD. (11) The BoD Business Committee certifies, based on surveys of the submitters' plans to market commercial implementations of the technology, that an implementation will be available within a year. (12) The BoD votes to make the technology an Adopted Specification. (13) An FTF conducts the first maintenance revision of the technology. (14) The FTF report is certified by the AB and recommended by its parent TC, and at least one submitter actually makes an implementation commercially available. (15) A vote of the BoD makes the technology an Available Specification. NOTE: The RFC process provides an alternative to steps 1 through 8. 
Technology Committee (TC): A body, chartered by the OMG Board of Directors, responsible for chartering Task Forces and recommending technologies for adoption to the BoD. There are two TCs in OMG: the Platform TC (PTC), that focuses on IT and modeling infrastructure related standards; and the Domain TC (DTC), that focus on domain specific standards. Sometimes used as a shorthand reference to the PTC and/or the DTC.
Telecommunications Platform Special Interest Group: An OMG subgroup chartered to communicate requirements from the Telecommunications Industry to the OMG subgroups and promote the use of OMG technologies as solutions to the needs of the Telecommunications Industry.
TestIF: Test Information Interchange Format
TF: See Task Force
Transformation: A model transformation specification determines how a set of output models results from a set of input models [MDA Foundation Document].  
Trial Member: OMG membership category that may send at most one representative to an OMG meeting, and subscribe to OMG email lists, but may neither vote (as the category name indicates) nor submit technology for adoption.
