Rome MultilingualWeb workshop report now available

A report summarizing the MultilingualWeb workshop in Rome is now available from the MultilingualWeb site. It contains a summary of each session with links to presentation slides and more detailed scribing done on site in Rome. Links to video for each session will be posted soon.
With approximately 150 attendees, the Rome Workshop focused on the theme “Making the Multilingual Web Work” and emphasized information about the best practices and standards that help content creators and localizers ensure that the World-Wide Web lives up to its name, across boundaries of language and culture. Attendees heard from a variety of perspectives, with fruitful dialogue between various stakeholder groups involved in trying to expand the multilingual scope of the Web.
Taking place over two days (12 and 13 March, 2013) at the headquarters of the UN’s Food and Agriculture Organization (FAO), the Workshop featured twenty-four conference-style presentations, seven poster presentations, and an “open space” discussion that featured six breakout sessions focusing on key topics that emerged during the Workshop. In addition, it showcased technology implementations of the forthcoming internationalization Tag Set (ITS) 2.0 standard.
The Workshop was sponsored by the EU-funded QTLaunchPad project and Verisign. It was run by the MultilingualWeb-LT Working Group.

New article: Unicode Bidirectional Algorithm basics
Unicode Bidirectional Algorithm basics is a repackaging of the initial part of “What you need to know about the bidi algorithm and inline markup” as a standalone article. It provides a gentle introduction to the behaviour of the Unicode Bidirectional Algorithm, and helps you understand why bidirectional text in Arabic, Hebrew, Thaana, Urdu, etc. behaves the way it does.

4 new articles about working with HTML markup in Arabic, Hebrew and Other Right-to-left Scripts
Creating HTML Pages in Arabic, Hebrew and Other Right-to-left Scripts
This tutorial has been modified to bring it in line with the current tutorial format. Rather than contain duplicate content, it now introduces the novice to key concepts and points off to useful further reading in an organized fashion. It has been completely rewritten.
Text direction and structural markup in HTML
This article has been created from material formerly in the tutorial “Creating HTML Pages in Arabic, Hebrew and Other Right-to-left Scripts” and augmented with information about new HTML5 markup constructs that are beginning to see adoption. It should be regarded as a new article, focusing on applying bidi markup to document- and block-level content, including forms.
What you need to know about the bidi algorithm and inline markup
This is an update of an existing article, but it has been almost completely rewritten. The most significant changes are the new parts describing how to apply the new HTML5 constructs which are beginning to see adoption. Additional changes will be needed as HTML5 bidi markup is finalised over the coming months. The article also proposes a simpler way to approach markup of bidi text, particularly useful for those with less experience, that relies less on a deep understanding of the issues involved.
Visual vs. logical ordering of text
This is a new article created from material that has been removed from the previously mentioned articles. It was removed into a separate article because visual ordering is much less important these days, and to avoid duplication. Only a few changes have been made to the content itself.
UTC Document Register Now Public
The Unicode Technical Committee (UTC) document register is now freely available for public access. This change has been made to increase public involvement in the ongoing deliberations of the UTC in its work developing and maintaining the Unicode Standard and other related standards and reports. Open access to the document register makes it easier to search both current and historical documents for topics of interest, using widely available search engines. The UTC document register contains online documents dating back to 1997 and online registers for paper document distributions dating back to 1991.
