General Information

Technologies must be operated and maintained in accordance with Federal and Department security and privacy policies and guidelines. More information on the proper use of the TRM can be found on the TRM Proper Use Tab/Section.

Description:	Extensible Markup Language (XML) Base specifies how base Uniform Resource Identifier (URI) info is to be embedded in XML documents. XML Base defines a single XML attribute to identify a base URI other than the base URI of the document that may be used to interpret relative URI references attached to XML document elements. This standard allows users to explicitly specify a document`s base URI for the purpose of resolving relative URIs in links to external images, applets, form-processing programs, style sheets, and so on.
Technology/Standard Usage Requirements:	Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.

The VA Decision Matrix displays the current and future VA IT position regarding different releases of a TRM entry. These decisions are based upon the best information available as of the most current date. The consumer of this information has the responsibility to consult the organizations responsible for the desktop, testing, and/or production environments to ensure that the target version of the technology will be supported. Any major.minor version that is not listed in the VA Decision Matrix is considered unapproved for use.

Legend:

White	Approved: The technology/standard has been approved for use.
Yellow	Approved w/Constraints: The technology/standard can be used within the specified constraints located below the decision matrix in the footnote[1] and on the General tab.
Gray	Unapproved: This technology or standard can be used only if a POA&M review is conducted and signed by the Authorizing Official Designated Representative (AODR) as designated by the Authorizing Official (AO) or designee and based upon a recommendation from the POA&M Compliance Enforcement, has been granted to the project team or organization that wishes to use the technology.
Orange	Divest: VA has decided to divest itself on the use of the technology/standard. As a result, all projects currently utilizing the technology/standard must plan to eliminate their use of the technology/standard. Additional information on when the entry is projected to become unapproved may be found on the Decision tab for the specific entry.
Black	Prohibited: The technology/standard is not (currently) permitted to be used under any circumstances.
Blue	Planning/Evaluation Constraint:The period of time this technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. If a customer would like to use this technology, please work with your local or Regional OI&T office and contact the appropriate evaluation office displayed in the notes below the decision matrix. The Local or Regional OI&T office should submit an inquiry to the TRM if they require further assistance or if the evaluating office is not listed in the notes below.

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.

General Analysis

Adoption Benefits

This is a mature standard.
At the time of writing, no National Institute of Standards and Technology (NIST) vulnerabilities had been reported and no VA Cyber Security Operations Center (CSOC) bulletins had been issued for the latest versions of this standard.
This standard specifies base URIs for Extensible Markup Language (XML) document elements, which removes the restriction requiring all relative links to be relative either to the base document URI or to the base URI of an external entity.
This standard supports Extensible Markup Language (XML) and XLink World Wide Web Consortium (W3C) XML document standards.

Adoption Risks

There has been no recent development activity on this standard.

Architectural Benefits

This standard is a modular specification that allows other standard specifications to incorporate Extensible Markup Language (XML) Base as a normative reference.
