SAMP: Application Messaging for Desktop and Web Applications

Mark Taylor (Bristol University)


SAMP, the Simple Application Messaging Protocol, is a technology which allows tools to communicate. It is deployed in a number of desktop applications including ds9, Aladin, TOPCAT, World Wide Telescope and numerous others, and makes it straightforward for a user to treat a selection of these tools as a loosely-integrated suite, combining the most powerful features of each, without requiring collaboration between the tool developers. It is widely used within Virtual Observatory contexts, but is also suitable for non-VO, or non-astronomical, use.

Enabling SAMP communication from web-based content has long been desirable. An obvious use case is arranging for a click on a web page link to deliver an image, table or spectrum to a desktop viewer, but more sophisticated two-way interaction with rich internet applications would also be possible. Use from the web however presents some problems related to browser sandboxing. We explain how the SAMP Web Profile, introduced in version 1.3 of the SAMP protocol, addresses these issues, and discuss the resulting security implications.
