Logical Data Model

MISMO is pleased to announce the release of our new Logical Data Model (LDM) for a 90-day public comment period.  The comment period will remain open from May 13th, 2019 until August 12th, 2019.  Any comments received will be reviewed and dispositioned. 

The new LDM is completely different from models previously issued by MISMO.  The LDM is platform independent and is intended to support any technology that a company might chose to utilize.  The new LDM will support XML, as MISMO has always done, but it will also support JSON, which is the technology of choice for mobile transactions.  As reference implementations of the new MISMO LDM are created in JSON and other technology formats, users will be able to utilize MISMO standards in technology formats best suited for their particular needs making it easier for organizations to communicate regardless of the technologies they choose to use. 

MISMO is in the process of developing an LDM specific logical data dictionary (LDD) to accompany the LDM which is expected to be available in the fall.

Created through MISMO's Logical Data Model Redesign Development Workgroup, MISMO's LDM was built using Unified Modeling Language (UML®) 2.5, a common standard created by the Object Management Group® that consists of an integrated set of diagrams that help users specify, visualize, construct and document software or business systems. The LDM is semantically equivalent to Version 3.5 of the XML Reference Model.  Going forward, all changes to  the XML Schema and other technology-specific products will be derivative products of the LDM.  

In addition to allowing public comment, the comment period is intended to afford participants who worked on the LDM standards and collateral at least thirty days' notice prior to the final release of these products to review them and disclose any applicable Patent Rights (as defined by MISMO's 2018 Intellectual Property Rights Policy).   

At this time, MISMO also requests that any non-participant organization that may have any patent or patent applications, or other intellectual property rights that might be infringed upon by an organization that uses or is compliant with these proposed MISMO products, disclose at this time in writing.   

All comments and disclosures should be directed to info@mismo.org.   

The MISMO LDM is provided for the purpose of providing an opportunity for comment on the product, as well as to afford an opportunity to disclose any applicable Patent Rights or other intellectual property rights, any other use of this product, including implementation, is prohibited at this time.   To access the proposed Logical Data Model Standards and Collateral, click on the following link: Logical Data Model Standards and Collateral
