Yes. CiNii is able to be linked to other websites and systems using OpenURL as follows:

(1) Institutions with fixed-price contracts are able to set links between their OPAC,　systems such as link resolvers (a system that links article information in a database to library OPACs or full text resources) and CiNii Articles by using OpenURL.
CiNii is compatible with OpenURL 1.0 and 0.1.
*Note: Only the administrators of the institutions with fixed-price contracts are able to set such links.
For details, see: About the OpenURL Sending Function.

(2) Describing a link in the OpenURL format enables links between each record on CiNii to link resolvers, etc.
For details, see: About the OpenURL Receiving Function for CiNii Articles, About the OpenURL Receiving Function for CiNii Books.
