Metadata for Research Projects as Grey Node Hubs for Literature Repository

Compared with regular publications, Information of research projects is a type of grey literature, Fortunately, many commercial or non-commercial research project databases have been used as important information resources by many research-based universities. The problem is: on one hand, though some of these research project databases include the outcome and funding information of projects, many are settled separated from the other databases even from being displayed on the website of libraries; on the other hand, much grey literature has strong relationship with one or more research projects, such as meeting or conference information, research data sets, proposals and funding information, etc.. This paper introduces research projects as grey node hubs for literature repository, and metadata of research projects under this vision.
