Journal of Women Medical and Dental College has electronic backup and preservation of access to the content of its journals via PKP Preservation Network (PKP PN). This can be seen at Publisher Manifest.
PKP has developed the PKP Preservation Network (PKP PN) to digitally preserve OJS journals. The PKP PN ensures that journals that are not part of any other digital preservation service (such as CLOCKSS or Portico) can be preserved for long-term access.
The PKP PLN is a dark archive. End users will not have access to the preserved content until after a trigger event. After a trigger event, PKP staff will approve the importing of the preserved content into one or more OJS instances hosted by PKP member institutions. Once loaded into these host OJS instances, the content will be available to the public under a suitable Open Access license. Which license depends on the copyright and licensing policies an OJS journal had in effect at the time the content was added to the PLN. The OJS plugin that packages content for preservation in the PLN will detect existing copyright and licensing configuration options and ask the journal manager to confirm them. Upon confirmation, the journal’s content is harvested into the PLN. Copyright and licensing information that applies to the content is preserved with it in the PLN, so that it will be easily available at the time of a trigger event. The four general categories of copyright and licensing options that apply to the dissemination of the OJS content after a trigger event are:
- the journal’s content is available under a Creative Commons license
- the journal’s content is available under a non-CC Open Access license
- the journal or publisher owns the copyright to the content and will be required to assign PKP the right to make it available under a CC license after a trigger event
- any other copyright/licensing arrangement (e.g., the journal is a toll journal and the publisher is not in a legal position to allow the content to be released under a CC license)
In all but the last of these situations, the journal content will be made available to the public after a trigger event by PKP and its partners under the same terms that applied before the trigger event. In the fourth situation, PKP will need to decide what the most appropriate means are to make the content available, including negotiating with the journal managers if they are available at the time of the trigger event. In practice, the vast majority of journals using currently OJS fall into the first three types.
