Balisage: where serious markup practitioners and theoreticians meet every summer. If you are happy to be the person in your project who understands the angle brackets and stuff, then you are a markup geek and Balisage is the place for you. Even if you are NOT a markup geek, if you find it instructive to spend time with them now and then, you will enjoy Balisage.

Balisage:
The Markup Conference

Virtual. Online. Technical. Interactive.
4 - 8 August 2025


Balisage is an annual conference devoted to descriptive markup, how to use it to best effect, and what it means for technology, access to information, and the preservation of information for the future.

Specific topics discussed vary over time, but the main themes of the conference consistently include:

  • markup languages, most visibly XML and SGML and proposals to extend or replace them, but also including other ways of structuring information
  • tools for processing marked-up documents
  • tools and practices for converting documents and other information from one format to another
  • systems and tools for managing changes in documents over time and space
  • experience reports from users and implementers
  • programming languages for writing tools for processing marked up data
  • issues relating to the theory of documents and markup
  • specific technologies related to any or all of the above: XML parsers, XSLT, XQuery, XPath, XForms, Invisible XML, XML editors, ...

We bring together people from a broad cross-section of those concerned with markup, from users who want to preserve their investment in information and make better use of their information, through to technical staff who design and manage complex information workflows, and to philosophers pondering the nature of documents and the meaning of the speech acts embedded in markup. Talks tend to be unabashedly technical.

If you work with markup or marked up data and want to learn from others who also do so, Balisage is for you.
