Decisions
Storage
As a DataCite datacenter you must make a few
initial decisions before you can begin to mint
DOIs for its datasets or documents.
As a DataCite datacenter you also commit to
ensure long-term storage of the objects, this
means for a minimum of ten years.
•
For which objects do you wish to mint DOIs?
- see guidance under DATA QUALITY
•
What would you want the DOIs to look like?
- see guidance under SUFFIX
•
What would be the best workflow in
your institution?
!
Maintaining the DOIs
Minting a DOI is also a commitment to maintain a
correct URL to the landing page and correct
metadata of the object.
!
CHECKLIST
Framework
________________________
RESOURCES
Landing pages
The URL of the DOI must always resolve to an
open accessible landing page that includes:
•
Metadata of the object
•
Access to the actual object
If the object is open access, the landing page
should provide a link to a direct full-text
download. If it is not open access, the landing
page should explain the access conditions
and provide a link to payment services or
other tools for gaining access.

Quality of the DOI system
Cite worthy
The quality of the DOI system relies on three
important elements:
A cite worthy object is an object that is worthy
of publication and can be useful to other
researchers in their work.
•
The research object must be cite worthy.
•
The research object must have well
described metadata.
•
!
The institution assigning the DOIs commits
to long-term storage of the object.
!
The datacenter is responsible for ensuring the
quality of the data to which they apply the DOIs.

DOI construction
Designing your suffix
Each DOI is unique and consist of two parts:
A prefix and a suffix.
When designing your suffix, you can go for
different strategies. You can either make a suffix
that makes sense for humans when they read it,
or one that is only suited for machines or
something in between.
The prefix is your institution’s identification
number. It is a six digit number and you will get
the prefix from DataCite Denmark. The suffix is
the part you can design yourself following a
few rules.
•
Each suffix must be unique
•
Only use the allowed characters
A-Z
a-z
0-9
- (dash)
. (dot)
_ (underscore)
: (colon)
/ (slash, but only if followed by alphanumeric)
The human oriented suffix has the advantage of
providing some information without resolving
the DOI. However, all suffixes are irreversible, so
if for example the name of your institution is
included and this changes in the future, the DOI
will not change accordingly.
The machine oriented suffix has the advantage
of being neutral, but does not provide any
information. Your institution is only identified by
the prefix.
EXAMPLES
Suffix
________________________
THE HUMAN ORIENTED DOI
In this construction the suffix includes the
name of the institution, the subject area
of the object and consecutive numbering.

________________________
THE MASCHINE ORIENTED DOI
Here the suffix is an arbitrary construction
of the allowed characters.

Prefix
Suffix
________________________
SOMETHING IN BETWEEN
A mix could be that the suffix includes
the name of the institution as well as
an arbitrary construction of the allowed
characters.

Providing the metadata
Metadata fields
The object’s metadata must be provided in an
XML file and shown on the landing page.
Depending on your object there are different
metadata fields about which you can find
detailed information on DataCite’s web.
!
Metadata are open access
The minimum requirements for all types of
objects are:
All DataCite metadata are open access and are
available for harvesting.
1) Identifier
- with type attribute
!
2) Creators
- with name identifier attributes
3) Title
- with optional type attribute
4) Publisher
5) PublicationYear

METADATA SCHEMA V. 3.0
The Metadata Schema v. 3.0 is the latest
schema and describes details for the
aquired XML file.
Choose › “Definition” to see the XML file.
Choose › “Documentation” to see the
description of the different elements.
You can also find different examples
of XML files depending on your type
of object.

Manual minting
If you only need to mint a few DOIs, you can
do so without setting up the automatic API.
1) Login at http://mds.datacite.org.
2) Write the symbol and password.
You will get a welcome mail with this
information from DataCite and you are
asked to provide a password.
3) Choose › Register new Dataset.
4) Write the DOI (prefix and suffix).
5) Write the URL of the landing page.
6) Upload an XML file with the metadata
or paste the XML code directly into
the text box.
7) Press › Save.
8) Automatic check of the information is
provided including validity of the XML file.

Automatic minting
Connecting to the API
You can use the DataCite API to set up
automatic DOI minting for your institution.
The actual connecting to the API requires a
person trained in handling and adapting your
IT systems.
How the API is incorporated depends on your
institutionel IT systems and which minting
workflow you prefer.
!
!
If you do not have an IT skilled person in your
staff, you can hire help from DataCite Denmark read more under SUPPORT.

________________________
DATACITE API V. 2
DataCite now use a version 2 of the API,
where it is mandatory to upload the
metadata of the objects to which the
DOI points.
