• What does the OAMH protocol mean?
• What lies beyond the OAMH protocol?

The OAMH protocol is a low-barrier interoperability specification for the recurrent exchange of metadata between systems

OAI roots: advance interoperability of preprints as a means to promote their global acceptance
• What does the OAMH protocol mean in the preprint context?• Are there any steps to be taken beyond the OAMH protocol in the preprint context?
![Page 17: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/17.jpg)

What follows:
• Scholarly communication systems• The paper and PDF implementation• The attractiveness of preprints• An interoperable, decomposed scholarly communication system built around preprints?

It is -- at least -- legitimate to reflect on the possibility of a digital system for scholarly communication that is not merely a scanned copy of the paper system.
In order to free our minds: let’s forget about who has been doing what and how in the existing system.

Communication via preprints suggests the possibility of preprints being the starting point of a new value chain in which the raw material -- the non-certified preprint -- is in open access.
![Page 33: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/33.jpg)

• sustaining versus disruptive technologies;• disruptive technologies:• somehow perform worse than established ones• not accepted by core customer base• but: convenient, cheap, …
• disruptive technologies can create competition in an existing value network by creating a new one first.=> preprints as a disruptive technology

This urges us to think about:
• how the functions of a scholarly communication system can be implemented in a digital environment
• how the functions of a scholarly communication system can interoperate disregarding their implementation

So what about the library?[ back to the who does what question ]
![Page 45: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/45.jpg)

Within the existing system, Libraries are trying hard to optimize the output of a system with far from optimal input.
![Page 46: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/46.jpg)
herbert van de sompel
It has become increasingly difficult for Libraries to fullfill their fundamental role of safeguarding equity of access.
![Page 47: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/47.jpg)
herbert van de sompel
In the PDF version of the information chain, Libraries are aggregating the aggregators.
That is a lot of aggregating for a digital world.
![Page 48: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/48.jpg)
herbert van de sompel
At the core of the problems that Libraries are facing is the total dependancy on information held upstream in the information chain.
![Page 49: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/49.jpg)
herbert van de sompel
As such, there are numerous incentives for Libraries:• to rethink themselves• to be pro-active in exploring alternative mechanisms for scholarly communication
![Page 50: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/50.jpg)
herbert van de sompel
• Libraries are close to authors: • a great position to fullfill the registration function i.e. obtain institutional material• a great position to archive institutional material
• Libraries are fast at embracing new technologies• Libraries have very knowledgeable people• Libraries provide a level of redundancy in services that is no longer required in a digital environment• The Library as an institution that safeguardes equity of access has global representation
Libraries: the good news
![Page 51: The Roof is on Fire](https://reader036.fdocuments.net/reader036/viewer/2022062303/554bd1c8b4c905706a8b4cf9/html5/thumbnails/51.jpg)
herbert van de sompel
• As organizations Libraries are slow movers, hosted by slowly moving institutions• Libraries are slow to recognize the fact that a new technology may allow [or beg] for a new mode of operation• The -- information -- world runs on Internet time
Libraries: the bad news
