(1) ASLLRP DAI (Data Access Interface) - Web access to the National Center for Sign Language and Gesture Resources (NCSLGR) corpus: linguistically annotated ASL data (continuous signing), with multiple synchronized video files showing views from different angles and a close-up of the face and linguistic annotations available as XML.
Information about the data collection and annotation, and about development of the Web interface
Anotation conventions are documented in these two reports, and an updated version will be forthcoming in Spring 2012:

Coming soon: 2012 Annotation Conventions
(2) The data collection listed in (1) was created using SignStream® 2.2.2 (runs as a Classic application on older Macintosh systems) for linguistic annotation. CD-ROMs containing the SignStream files with linguistic annotations and the associated files are also available: http://www.bu.edu/asllrp/cd/ . (A new Java reimplementation of SignStream®, with many new features, is currently under development and scheduled for beta release by Spring 2012.)

(4) There are additional data available from the American Sign Language Lexicon Video Dataset (ASLLVD), which is a collection of almost 10,000 examples (of about 3,000 distinct signs, each produced by between 1 and 6 ASL signers) based largely on the entries in the Gallaudet Dictionary of American Sign Language.
