This paper explores how the use ofmultimedia communications technologies to enable elements of real-worldworking knowledge, that are tacit andembedded in working practices to be rendered into shareable forms forprofessional learning. Communications technology offers innovative ways forgeographically distributed professional communities to create, annotate,discuss and reflect upon multimediaobjects that capture working practices, such as problems of practice. Thepaper reports on work-in-progress on multimedia objects (primarilydigitised videoclips). Use of multimedia in professional learning isrelatively novel, and it is surfacing issues about the requirements for creating shareable, effective representations.Descriptors for multimedia objects have been developed and the paperfocuses on applying the descriptors to an example videoclip. The durationof the clip, it's use of artefacts and the social cues in the clip are considered key factors in creating ashareable representation for discussion and reflection in distributedprofessional communities.
