• All parties would benefit from support of standard APIs and data representations in order to enable TDM across both open access and subscription-based publishers. • Subscription-based publishers find it impractical to negotiate multiple bilateral agreements with thousands of researchers and institutions in order to authorize TDM of subscribed content.

• Researchers find it impractical to negotiate multiple bilateral agreements with hundreds of subscription-based publishers in order to authorize TDM of subscribed content.

Sustainability Model

• New initiatives are always optional to our members. Members who do not participate in our new initiatives will not be charged for them.

• We do not charge end-users (e.g. researchers, librarians) for access to metadata and APIs

• We sometimes charge intermediaries for access to our services (to cover the cost of administration, maintaining SLAs, etc.)

• We do not charge our members for depositing extra metadata into our services

• We sometimes charge our members for the cost of administering our services, maintaining SLAs, development, etc.

• We eschew charging mechanisms that involve complex administrative overhead. The cost of developing and running them generally negates the revenue raised by implementing them.

• We try to tie any charges as directly as possible to where costs are incurred.

We are using CrossRef's Prospect text mining API in the context of the Hiberlink project, which investigates reference rot in scholarly papers at a very large scale. The API is really straightforward and based on common technical approaches; it can easily be integrated in a broader workflow. In our case, we have a work bench that monitors newly published papers, obtains their XML version via the API, extracts all HTTP URIs, and then crawls and archives the referenced content. Currently, we can only access Elsevier papers via the API but as more publishers join Prospect, it will become a powerful, uniform one-stop-shop for text mining scholarly literature.

--Martin Klein and Herbert Van de Sompel, Los Alamos National Laboratory

I think this is a big step in the right direction and makes retrieving full text file a lot easier, I hope that publishers support it. --Maximilian Haeussler, UCSD

What do I need to do?

Publishers (required)

• Register full-text URLs with CrossRef

• Register <lic_ref> well-known license URIs with CrossRef

Publishers (optional)

• Register click-through proprietary licenses with Prospect click-through service

• Adapt platform APIs to handle Prospect API tokens

Researchers

• Register with Prospect and accept/decline licenses

• Modify TDM tools to look for <lic_ref> elements

• Modify TDM tools to make use of Prospect API token
