Re: [Handle-info] Question about the handle root

Indeed, the MPAs collectively manage the GHR service.  (See for example https://www.dona.net/handle-system .)  This information is publicly resolvable, for example http://hdl.handle.net/api/handles/0.NA/20.500?pretty .  As far as I know, there is no bulk download facility for GHR records.

Thank you very much for your reply. I have one more question.

I have learned that some data are synchronized and shared among MPA. For example, 20.500, which can be queried at MPA (20) and MPA (21) at the same time.
Is this data public or private?Can it be downloaded?

Thank you ！

Indeed, looking at the bootstrap_handles from the published source in the handle.net software downloads is right.

You can also obtain the data by performing the resolutions, for example
https://hdl.handle.net/api/handles/0.NA/0.NA?pretty

Best,

That's right, a handle client needs to bootstrap with some kind of
root info, so the two libraries at the client download area on
handle.net [1] have such files.  The Java library "Client Library
(ver. 9.3.0) — Java™ Version", for instance, uses the JSON file
src/main/java/net/handle/etc/bootstrap_handles .  Also, the C library
has a file called "root_info.c", however, this version is massively
outdated.
