The Legal Matter Standard Specification (LMSS) is an open taxonomy for the uniform description of legal proceedings and related processes and entities.[1]

LMSS has been accepted by legal matter management and legal case management software vendors to facilitate the interoperability of fragmented information systems.[2][3] It is published by the Standards Advancement for the Legal Industry (SALI) Alliance.

The LMSS taxonomy also been adopted by major legacy litigation alerting and analysis services.The American Lawyer's Law.com Radar service classifies federal and state filings according to the LMSS using machine learning with human review.[4][5] Fastcase similarly used natural language processing to apply LMSS-based tags to hundreds of millions of federal briefs, enabling analysis by motion, outcome, case type, jurisdiction, party, judge etc.[6][7] A legal tech startup released a web tool using OpenAI's service to automate tagging of legal data, in collaboration with SALI.[1][8]

Development

edit

SALI was established in 2017 by the Legal Marketing Association (LMA) and Association of Legal Administrators with support from the Association of Corporate Counsel and US law firms and their clients.[9][10][1]

The release of Version 1 of the LMSS was announced on January 29, 2019 at the office of the software giant Microsoft.[10][11] It was received as "one of the most significant announcements at Legaltech19."[12] Early portions of the taxonomy stem from major legacy legal information services vendor, Bloomberg Law.[13]

Version 2 of LMSS, released in March 2022, expanded the taxonomy to include business terms of matters, milestone events, and additional state court codes. Customization for Canada and cross-references to related standards (see below) were also added.[7]

In May 2022, the LMSS was adopted by Bloomberg's top competitor, Thompson Reuters.[14]

The standard was forked in August 2024, initially under the name SOLI and later as FOLIO.[15][16]

edit

For coding tasks, especially for billing purposes, the LMSS augments the Uniform Task-Based Management System (UTMB) released in the mid-1990's with support from the American Bar Association and the Association of Corporate Counsel.

LMSS provides granularity beyond the "Nature of Suit" (NOS) codes used by PACER for federal suits, and extending uniform tagging to state courts.[4][5][7]
