Extremely Annotational RDF Markup (EARMARK) is a meta-syntax for non-embedded markup that can be used for stand-off annotations of textual content with fully W3C-compliant technologies.
This document represents the EARMARK ontology definition of the shell classes i.e., all those classes that must be used to define all the elements, attributes, comments, text nodes and hierarchies among them.
Extremely Annotational RDF Markup is a meta-syntax for non-embedded markup that can be used for stand-off annotations of textual content with fully W3C-compliant technologies. EARMARK is based on an ontologically precise definition of markup that instantiates the markup of a text document as an independent OWL document outside of the text strings it annotates, and through appropriate OWL and SWRL characterizations it can define structures such as trees or graphs and can be used to generate validity constraints (including co-constraints currently unavailable in most validation languages).
IRI: http://www.essepuntato.it/2008/12/earmark#Comment
A markup item identifying a comment, as the item containing the string 'This is a comment' in the following XML excerpt:
IRI: http://www.essepuntato.it/2008/12/earmark#Element
A markup item identifying an element, as the item 'img' in the following XML excerpt:

IRI: http://www.essepuntato.it/2008/12/earmark#PointerRange
A range that refers to any text lying between two non-negative integer locations that identify precise positions withing a docuverse.
Each location of this kind of range refers to a point before or after a particular character. For instance, taking into consideration the string 'This is an example' contained by a docuverse, the location '0' is immediately before the first character 'T', location '1' is immediately after the character 'T' and before the character 'h', the location '2' is after the character 'h' and before 'i', and so on.
Note that these ranges allow to define (considering the string 'a devil' as content of a docuverse as example):
IRI: http://www.essepuntato.it/2008/12/earmark#StringDocuverse
A docuverse that specifies all its content in form of a string, such as 'This is the string the docuverse represents.'.
IRI: http://www.essepuntato.it/2008/12/earmark#URIDocuverse
A container of strings that may appear in the document, such as the URL 'http://www.essepuntato.it/2008/12/docuverse.txt' that contains the string 'This is the string the docuverse represents.'
IRI: http://www.essepuntato.it/2008/12/earmark#XPathPointerRange
A range that refers to any text, obtained from a particular xpath context starting from a docuverse content, lying between two non-negative integere locations that identify precise positions.
This kind of range allows to define specific positions, as explained for the class 'PointerRange', within the concatenation of strings obtained by applying the xpath context to the docuverse the range refers to, as introduce in the class 'XPathRange'.
For instance, considering the following docuverse content:
<root><p>No devil </p><p>lived on</p></root>
the range defined on that docuverse as xpath_context = '//p', begin = '0', end = '17' refers to the text 'No devil lived on'.
NB: if we define a standard pointer range on the same docuverse using the same begin and end locations of the previous one, what we obtain as text will be
<root><p>No devil
IRI: http://www.essepuntato.it/2008/12/earmark#XPathRange
A range that refers to any text, obtained from a particular xpath context starting from the docuverse content, lying between two locations that identify precise positions.
The semantics of this kind of range is the following:
IRI: http://www.essepuntato.it/2008/12/earmark#hasXPathContext
It defines a particular xpath context for the range.
