URI::OpenURL

URI::OpenURL is a Perl module that implements OpenURLs encoded as URIs in Key/Encoded-Value (KEV) Format. It is important to note that this module is only a part of the OpenURL specification and does not verify that OpenURLs constructed comply with the OpenURL specification. In many cases, the sanity of the constructed OpenURLs will depend on the community of use.

According to the implementation guidelines, a ContextObject is a bundled description of the referenced resource and the associated resources. When a user clicks a link, it is the ContextObject that is transported by the system. A KEV OpenURL should contain only one ContextObject, which may contain up to six entities. The Referent, which provides information about the referenced item, must always be included in a ContextObject. The other entities, including ReferringEntity, Requester, Resolver, ServiceType, and Referrer, hold information about the reference context and are optional.

Overall, URI::OpenURL can be a useful tool for implementing OpenURLs encoded as URIs in KEV format, but it is important to be mindful of the construction of OpenURLs and their compliance with the OpenURL specification.
