The LexML is a joint initiative of the Civil Law legal system countries seeking to establish open standards for the interchange, identification and structuring of legislative and court information, especially official documents.

Participated in this initiative are Germany, Brazil, Spain, Italy, through local institutions, with the goal of convergence of national standards and the international standardization of some instruments, such as URN LEX and the use of XML formatting standards and the exchange of its metadata.

One of the initial goals of the initiative, later abandoned, was the standardization of a single language (called LexML) for marking of legal normative documents of all participating countries. The name "LexML" derives "lex" prefix (Law in Latin) and the acronym ML (English Markup Language) used as a suffix in XML markup languages schemes.

Currently only Brazil LexML initiative called "LexML" to its XML schema. Other former participants migrated to Akoma Ntoso and EUR-Lex. [1]

Markup language Modern system for annotating a document

Markuplanguage refers to a text-encoding system consisting of a set of symbols inserted in a text document to control its structure, formatting, or the relationship between its parts. Markup is often used to control the display of the document or to enrich its content to facilitate automated processing. A markup language is a set of rules governing what markup information may be included in a document and how it is combined with the content of the document in a way to facilitate use by humans and computer programs. The idea and terminology evolved from the "marking up" of paper manuscripts, which is traditionally written with a red pen or blue pencil on authors' manuscripts.

Standard Generalized Markup Language Markup language

The Standard Generalized Markup Language is a standard for defining generalized markup languages for documents. ISO 8879 Annex A.1 states that generalized markup is "based on two postulates":

XML Markup language by the W3C for encoding of data

Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.

RuleML is a global initiative, led by a non-profit organization RuleML Inc., that is devoted to advancing research and industry standards design activities in the technical area of rules that are semantic and highly inter-operable. The standards design takes the form primarily of a markup language, also known as RuleML. The research activities include an annual research conference, the RuleML Symposium, also known as RuleML for short. Founded in fall 2000 by Harold Boley, Benjamin Grosof, and Said Tabet, RuleML was originally devoted purely to standards design, but then quickly branched out into the related activities of coordinating research and organizing an annual research conference starting in 2002. The M in RuleML is sometimes interpreted as standing for Markup and Modeling. The markup language was developed to express both forward (bottom-up) and backward (top-down) rules in XML for deduction, rewriting, and further inferential-transformational tasks. It is defined by the Rule Markup Initiative, an open network of individuals and groups from both industry and academia that was formed to develop a canonical Web language for rules using XML markup and transformations from and to other rule standards/systems.

The Theological Markup Language (ThML) is a "royalty-free" XML-based format created in 1998 by the Christian Classics Ethereal Library (CCEL) to create electronic theological texts. Other formats such as STEP and Logos Library System (LLS) were found unacceptable by CCEL as they are proprietary, prompting the creation of the new language. The ThML format borrowed elements from a somewhat similar format, the Text Encoding Initiative (TEI).
