Digital Object Identifiers

The ADS uses the Digital Object Identifier (DOI) System for uniquely identifying its digital content. The DOI System is an ISO International Standard and managed by an open membership consortium including both commercial and non-commercial partners.

DOIs are persistent identifiers which can be used to consistently and accurately reference digital objects and/or content. Within the ADS, DOIs are used to reference digital archives, and in the future selected individual digital files. The DOIs provide a way for the ADS resources to be cited in a similar fashion to traditional scholarly materials. DOIs can be thought of as a combination of a URL and an ISBN number.

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 an archive's DOI to be permanent while the actual location of the archive can change. In this sense, 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 archive.

The ADS DOIs look like 10.5284/xxxxxxx where the suffix 'xxxxxxx' is a random but unique number. The DOI can then be resolved by the DOI Resolver

ADS Archives can be searched by DOI, simply type the DOI into the Archives keyword search on the left of the page and the relevant archive will be returned by the search.

Citing DOIs

See DCC JISC Guide on How to Cite Datasets and Link to Publications for insight into the evolving standards in this field. Further examples can be found here and here.

DOIs should be the last element in a citation irrespective of the format used. The DOI citation should begin with "doi:" in lowercase followed by the DOI with no spaces between the colon and the DOI.


Sample Citation

Southampton City Council (2013) Chapel, Royal South Hants Hospital, Fanshawe Street, Southampton (SOU1570) (data-set). York: Archaeology Data Service (distributor) (doi:10.5284/1018074)

DOIs can also be cited as a persistent link from another Web page. This is done by appending the DOI Resolver with the DOI. This would look like:

However, if it is possible, it is best to hide the URL in the href property of the <a> tag and have the link text be of the form doi:10.5284/1000000. The HTML for this would look like:
