Results of the scientific research - scholarly products - are not homogenous. They appear in different forms during different research activities and might be described with several related concepts. First one is the research workflow, which consists of several phases: from searching of the relevant information through data collecting to dissemination of the results. Every phase characterized by the activities, which described by scholarly primitives and the research products are the results of this activities. Second, the research products itself are represented by information of different types: content, data and knowledge. For example, during searching of the relevant information scientist produce several types of information: collection of papers/datasets/etc, several facts, derived from them, and research hypothesis, which express researcher’s personal ideas. For producing them modern scientists use research tools (the third concept), which could be distinguished by the information type too, but not always one-by-one: for example, most of the reference management programs are not only storing the papers, but also maintaining the work on the text reading. One more related concept - information availability, reflects openness and discoverability of the scholarly products and might be to the different degree supported by the instruments. We put these four concepts into the information model of the scholarly products, which will be helpful for managing research results.
