Collaboration via virtual communities of practice (VCops) is one of the most important future strategies for the strengthening of global efforts for a collaboration environment. This paper presents building a virtual community of practice (Ontocop) as knowledge resources for building ontology of information science. The paper explains structural components of this community and the manner in which the participants will interact. How to encourage people to participate and interact and which methods they could use. This ontology of information science is preceded by developing a taxonomy or thesaurus of information science. It explains methods to build the ontology based on the outcome of experts’ interaction: firstly collecting discussion ideas in MySql database and annotation the gathered data. Secondly: building the ontology using OWL language and protégé editor. Access to the ontology will facilitate knowledge in a specific domain and speed up information retrieval.
