The IVOA Simple Image Access version 2 protocol defines an easy way to provide community access to a collection of data. At the Vera C. Rubin Observatory we currently enable ObsTAP access to our data holdings via an ObsCore export or view of our Data Butler repositories. This approach does come with some deployment constraints, such as requiring pgsphere and compatibility with our CADC TAP implementation, so recently we decided to see whether we could instead provide an SIAv2 service that talks directly to our Data Butler. Here we describe our motivation, implementation strategies, and current deployment status, as well as discussing some metadata mismatches between the Butler data models and SIAv2.

A table of the technote's acronyms and their definitions are maintained in the acronyms.tex file, which is committed as part of this repository.
To update the acronyms table in acronyms.tex:
make acronyms.tex
Note: this command requires that this repository was cloned as a submodule.
The acronyms discovery code scans the LaTeX source for probable acronyms. You can ensure that certain strings aren't treated as acronyms by adding them to the skipacronyms.txt file.
The lsst-texmf repository centrally maintains definitions for LSST acronyms. You can also add new acronym definitions, or override the definitions of acronyms, by editing the myacronyms.txt file.
lsst-texmf includes BibTeX files, the lsstdoc class file, and acronym definitions, among other essential tooling for LSST's LaTeX documentation projects.
To update to a newer version of lsst-texmf, you can update the submodule in this repository:
git submodule update --init --recursive
Commit, then push, the updated submodule.
