Dear all,
This is a follow up to our message sent in early February on the
implementation of Digital Object Identifiers (DOIs) at the ADS. The ADS
will be taking responsibility for creating ('minting') these references from
the 13th June, we therefore require any comments or queries that this
important new development might create to be resolved before this date.
For information, the full text of the original message is given below.
In association with the DataCite project based at the British Library, the
ADS has embarked on a programme to use the DOI System to identify, uniquely,
its digital content. DOIs are persistent identifiers which can be used to
consistently and accurately reference digital objects and/or content. By
associating DOIs with its holdings, the ADS will provide its users with a
unique identification system which can be used when referencing its
resources. Within the ADS, DOIs are now being used to reference digital
archives, and, will in the future, be used to reference selected individual
digital files. The DOIs provide a way for the ADS resources to be cited in a
similar fashion to traditional scholarly materials, and in that sense, DOIs
can be thought of as a combination of a URL and an ISBN number.
The DOI System is an ISO International Standard and managed by an open
membership consortium including both commercial and non-commercial partners.
Each DOI has metadata associated with it, such as subject, location
(URL),publisher, creator, etc. While the metadata can change for a DOI, the
actual DOI name will never change. This allows for a resource's DOI to be
permanent while the actual location of the resource can change. Citing a DOI
is much more robust and permanent than merely citing a URL, since the DOI
will always resolve to the current location of the resource. The ADS DOIs
look like 10.5284/xxxxxxx where the suffix 'xxxxxxx' is a random number. The
DOI can then be resolved by using the DOI Resolver http://dx.doi.org, which
acts as a look-up service for the current location of the digital object.
For example: The ADS resource "Chapel of St Laurence, Bradford on Avon
currently has a URL of
http://archaeologydataservice.ac.uk/archives/view/bradford_na_2010/, its DOI
is doi:10.5284/1000123 and this is what should be cited for this dataset,
however to provide a hyperlink to this the resolver and the DOI are
concatenated like this http://dx.doi.org/10.5284/1000123 .In future it is
expected that most browsers will automatically recognise the doi: suffix so
that the resolver address will not be necessary (e.g. Chrome and Firefox
have plug-ins to do this already).
In addition to the traditional archive holdings of the ADS, we have recently
allocated DOIs to Grey Literature reports we host within the Grey Literature
Library. This means that your reports can be consistently cited and
universally located by using the DOI System. Each Grey Literature report in
our library will receive a DOI which will always resolve to the landing page
of that report. The landing pages are the metadata pages which contain
links to the actual reports, such as:
http://archaeologydataservice.ac.uk/archives/view/greylit/details.cfm?id=362

Within a DOI System there can only be one DOI per conceptual object. In
terms of the ADS, a conceptual object can be one of our archives (which
contains many other digital objects and metadata), a Grey Literature report
(which contains the report documents and metadata), or an individual file.
Since the DOI System can break down if there are multiple DOIs for the same
conceptual object (think of multiple ISBN numbers for the same book), we
would like to know if you already have DOIs for your Grey Literature reports
or are planning to 'mint' your own DOIs. If you already have DOIs for your
Grey Literature please let us know and we will add that DOI to our metadata
rather than create a new DOI for the same report.
By giving an ADS provided DOI to your Grey Literature report there is no
change in ownership or copyright of the Grey Literature, it is merely a way
to provide users with a persistent identifier to easily find and cite your
work. Neither does this affect our commitment to maintain stable permanent
URLs where we have agreed they will appear in publications. If you have any
questions about our use of DOIs or would like further information, please do
not hesitate to contact us or follow the links below for more information.
Best regards,
The ADS
