VirtualObservatorySAMP

This package provides a Julia implementation of the Simple Application Messaging Protocol (SAMP), a messaging protocol that enables astronomy software tools to interoperate and communicate (see also Taylor et al. 2015).

Currently, the package implements only the non-callable client interface: this allows one to send synchronous message to SAMP-aware applications such as SAOImage DS9, TOPCAT, Aladin Sky Atlas and similar.

The package can also connect using a WEB hub provided, for example, by Aladin lite.

Example

Open TOPCAT and, then, SAOImage DS9 on your local computer.

Then type the following commands on the Julia REPL:

julia> using VirtualObservatorySAMP

julia> hub = SAMPHub();

julia> client = register(hub, "Test"; 
       description="Simple test of VirtualObservatorySAMP.jl", version=v"1.0.0");

julia> ds9 = first(getSubscribedClients(client, "ds9.get"))
"c2"

julia> getMetadata(client, ds9)
