Knowledge sharing filtering on OAI-PMH

There are three kind of protocols available to establish knowledge sharing between agents like knowledge management system, web page, and expert system. All these three protocols are OAI-PMH, Semantic Web, and KQML. OAI-PMH developed and used by librarians as an excerpt of each document and it can be used as knowledge sharing system on metadata level. This is also the reason why PMH stands for Protocol for Metadata Harvesting. OAI-PMH make any data provider agents become open for any other harvester agents to harvest their metadata, as intended by Open Archives Initiatives. However, as open as their intention, there are some circumstances where some specific metadata are only intended for a specific harvester. Thus, this research propose a mechanism where a data provider can restrict access through credential filtering.
