Version:   beta 0.3
 
 This schema provides for creating relationships between items represented by crossref DOIs and other items that may 
 be defined by a DOI (crossref or other RA) or by some other identifier. New relation types will be added as they're needed.
 Please contact support@crossref.org to request additions or changes.
 
 Certain relationship types are covered elsewhere in the main deposit schema due primarily to specific processing or 
 the need to logically group those relations alongside other relevant metadata. For example cited-by relations are 
 created by the deposit of a citation_list. Crossmark->Updates addresses relationships between DOIs where a primary 
 item is updated, revised, hasErratum, withdrawn ... etc.  When constructing relations please be sure to use the 
 the most appropriate metadata structure.
 
 Relationships between DOIs in crossref are established bidirectionally between those DOIs making it unnecessary to
 deposit relationship metadata for both DOIs.
 Example: 
       DOI A metadata contains 'hasTranslation' with a target of DOI B will automatically
       make this claim visible in metadata for B.
       Seen from the perspective of B: A claims it hasTranslation of which B is the target of the claim.
 
 Change history: 
 10/3/14  CSK   removed reg-agency attribute. This is not necessary, can be derived from the DOI
 10/3/14  CSK   split into inter and intra relation elements
 10/3/14  CSK   pulled in common crossref schema for description element and language attributes 
 12/21/16 CSK   added comments to each relation type indicating the appropriate inverse relation type
 3/6/17 PDF added accession as identifier-type
 
 ====== C O N V E N T I O N ==============================================================================================
 Relationships between two objects have an implicit directionality that in natural language terms dictate which object is the actor
 and which is acted-upon.  This directionality is semantically based on the relationship name. Crossref's model makes
 no attempt to automatically 'understand' this semantic. 
 
 The identifier parent to the PROGRAM element is considered the claimant of the relationship (e.g. the entity that
 establishes the relationship).
 
     yes:  10.1234/abcd references 10.5678/efgh    =>  10.1234/abcd claims that it references 10.5678/efgh
     yes:  10.1234/abcd referencedBy 10.5678/efgh  =>  10.1234/abcd claims that it is referenced by 10.5678/efgh

Element timestamp

Namespace

http://0-www.crossref.org.brum.beds.ac.uk/relations.xsd

Annotations

Indicates version of a batch file instance or DOI. timestamp is used
to uniquely identify batch files and DOI values when a DOI has been updated one or
more times. timestamp is an integer representation of date and time that serves as a
version number for the record that is being deposited. Because CrossRef uses it as a
version number, the format need not follow any public standard and therefore the
publisher can determine the internal format. The schema format is a double of at
least 64 bits, insuring that a fully qualified date/time stamp of 19 digits can be
submitted. When depositing data, CrossRef will check to see if a DOI has already
been deposited for the specific doi value. If the newer data carries a time stamp
value that is equal to or greater than the old data based on a strict numeric
comparison, the new data will replace the old data. If the new data value is less
than the old data value, the new data will not replace the old data. timestamp is
optional in doi_data and required in head. The value from the head instance
timestamp will be used for all instances of doi_data that do not include a timestamp
element.

The edition number of a book. edition_number should include only a

"3", not "third edition" or "3rd edition". Roman numerals are acceptable. Publishers
will update a print edition with a new edition number when more than ten percent of
the content has changed. However, publishers expect to continuously update online
editions of books without changing the edition number.<i>The ability to update the electronic version independent of the print version could be problematic for researchers. For example, if a research article cites the print version of a chapter, and a researcher subsequently links to the online version of the same chapter, the content may be different from the print version without the typical indication of a new edition. This topic requires further discussion outside of the scope of this specification.</i>

Annotations

The issue number in which an article is published. Only one issue
name should be used for the issue. The issue number takes precedence over any other
name. For example, if an issue has only a seasonal name, then the season should be
listed in issue. However, if an issue has a number and a season, then only the
number should be listed in issue, and the season should be placed in month (see the
table in month, below, for proper encoding of the season) if the specific month of
publication is not known. Do not include the words "issue", "No" or "number" in this
element. When submitting DOIs for journal articles published online ahead of print,
you should submit the issue number, when known, even if the pagination information
for the entity is not yet known. Data may be alpha, numeric or a combination.

contains the doi, timestamp (version) and corresponding resource (URI) data for the
doi. Cases of single-resolution (i.e. one DOI with a single corresponding URI)
should be tagged with a doi/resource pair in doi_data. If additional resources are
to be proved the <collection> element may also be used. The single URL
provided in the <resource> is mandatory and serves as the single resolution
target for the DOI. Note: A timestamp value placed inside doi_data will override any
timestamp value placed in the <head> element.

DOI for an entity being registered with CrossRef.  In 2008 CrossRef restricted DOI suffix 
characters to the following: "a-z", "A-Z", "0-9" and "-._;()/" 
				
Existing DOIs with suffix characters outside of the allowed set are still supported.  For additional
information on DOI syntax, see http://0-help.crossref.org.brum.beds.ac.uk/#ID5755

Annotations

The element that contains a URI associated with a DOI. URLs are
referred to as resources in the 2.0 CrossRef schema because they can be any valid
URI. Cases of single-resolution (i.e. one DOI with a single corresponding URI)
should be tagged with a doi/resource pair in doi_data. Only one resource is allowed
per doi_data, the exception being resource elements within a collection element.
Values for the "content_version" attribute are vor (version of record) and am
(advance manuscript).

Annotations

A collection is a container for one or more items each holding a doi
or a resource (URI) which is related to the DOI in the ancestor <doi_data>
element. A collection must be qualified by a property attibute or the
multi-resolution attribute. property attributes: list-based: uses an interim page
and presents the list of items to the user (via Multiple Resolution) country-based:
proxy picks destination based on the country code of the user's location (this
option is not currently active, contact support@crossref.org for more info)
crawler-based: identifies resource to be crawled by the specified crawlers.
text-mining: identifies resource to be used for text and data mining unspecified:
identifies resource with unspecified usage syndication: identifies resource to be
used for syndication The multi-resolution attribute may be used to lock or unlock
DOIs for multiple resolution.

The sub-title portion of an entity title. When possible, it is better
to tag a title and subtitle with separate elements. If this information is not
available, it is acceptable to submit the title and subtitle all within the title
element with punctuation (preferably a colon) used to separate the subtitle from the
title. When a subtitle is tagged, the space and punctuation between the title and
subtitle text should not be included. The following examples illustrate correct and
incorrect tagging practices: Correct and optimal tagging:<title>The Human Brain</title>

Namespace

http://0-www.crossref.org.brum.beds.ac.uk/relations.xsd

Annotations

Month of publication. The month must be expressed in numeric format
rather spelling out the name (e.g.. submit "10", not "October"). The month must be
expressed with a leading zero if it is less than 10 (e.g. submit "05", not "5").
When a journal issue has both an issue number and a season, the issue number should
be placed in issue. If the month of publication is not known, the season should be
placed in month as a two-digit value as follows: Season Value Spring 21 Summer 22
Autumn 23 Winter 24 First Quarter 31 Second Quarter 32 Third Quarter 33 Fourth
Quarter 34 In cases when an issue covers multiple months, e.g. "March-April",
include only the digits for the first month of the range.
