Great to hear, the number of liberally licensed implementations of LLSD is up to five now (including the C# implementation in the libomv repository). Is an up to date PHP implementation on Linden's roadmap, or would it make sense for someone else to start porting one of these implementations to PHP?

Subject: [vwrap] Linden Lab open source LLSD code

I'm happy to announce that Linden Lab has open sourced (MIT licensed) its LLSD implementations in four languages: C++, JavaScript, Haskell, and Python. The code can be found here:
            http://hg.secondlife.com/llsd

Please let me know if this is useful, and if you need any help using it.

Linden Lab LLSD Libraries

    v1 - 2010-06-07 - Joshua Bell & Mark Lentczner


ABOUT
=====

LLSD is defined in draft-hamrick-vwrap-type-system-00. It is a structured data
system used for interchange. See the draft for more details:

    http://tools.ietf.org/html/draft-hamrick-vwrap-type-system-00

The design and development of LLSD is being undertaken by the IETF VWRAP
working group. Please direct design and development questions to its mailing
list.

    wiki - http://trac.tools.ietf.org/wg/vwrap/trac/wiki
    list - https://www.ietf.org/mailman/listinfo/ogpx

This distribution contains Linden Lab's open source (MIT licensed)
implementations of the LLSD type system in four langauges:

    C++         LLSD
    JavaScript  LLSD & LLIDL
    Haskell     LLSD & LLIDL
    Python      LLSD & LLIDL (*)

There are four directories, one per file, and each has its own README file with
details for building and using the code. All versions have unit tests.

Questions regarding these libraries can be directed to Josh or Mark:
    josh@lindenlab.com<mailto:josh@lindenlab.com>
    markl@lindenlab.com<mailto:markl@lindenlab.com>

Linden Lab hopes that by releasing these open source, it will help facilitiate
the development of LLSD, as well as ease interoperatibility with currently
deployed systems that use LLSD such as Second Life and OpenSim.

    - Josh & Mark

(*) The Python version is currently distributed in a separate repository:
    http://hg.secondlife.com/llbase/
The intention is to eventually migrate it here.
