You can submit here your contributed talk/topic for the IVOA Interoperability Meeting.
Contributions are considered, by default, as presentations of 10'-12' with 3'-5' minutes of Q&A time. There's not limit to the number of contributions you could submit but the number of sessions and session length is fixed, so consider submitting your contributions as soon as possible to help organizing the programme.
A title and abstract, plus a speaker are required, as well as a preferred time slot for it (time zone dependent). You can optionally also set the WG/IG topic you feel your contribution better fits in.
