A file (XML, PFD, plain text) which contains the Redaction and, likely, other type of analytical information. Taking as example the poem "Amadís de Gaula a Don Quijote de la Mancha": Redaction could be an XML-TEI file (for example, the TEI annotated text of ADSO corpus (https://github.com/bncolorado/CorpusSonetosSigloDeOro/blob/master/Cervantes/Cervantes_1.xml)), whereas "additionalFile" could be another file containing a plain text version of the same poem.
additional File
An additional name, such as a nickname, epithet, or alias, or any other descriptive phrase used within a personal name. Taking as example the writer Charlotte Brontë, an "additionalName" would be her alias: "Currell Bell".
additional Name
Contains a postal address, for example of a publisher, an organisation, or an individual. There can only be one address per Organization. Taking as example Cervantes' poem "Amadís de Gaula a Don Quijote de la Mancha", TEI-annotated in the ADSO corpus, the publisher would be "Natural Language Processing Group. Department of Software and Computing Systems. University of Alicante (Spain)", and its address would be "carretera San Vicente s/n 03690 San Vicente del Raspeig, Alicante (Spain)".

audience Education Level
An account of a person's life written, composed, or produced by another. Taking as example the poet Antonio Machado, "biography" could be: "Antonio Cipriano José María y Francisco de Santa Ana Machado y Ruiz (26 July 1875 – 22 February 1939), known as Antonio Machado, was a Spanish poet and one of the leading figures of the Spanish literary movement known as the Generation of '98. His work, initially modernist, evolved towards an intimate form of symbolism with romantic traits. He gradually developed a style characterised by both an engagement with humanity on one side and an almost Taoist contemplation of existence on the other, a synthesis that according to Machado echoed the most ancient popular wisdom. In Gerardo Diego's words, Machado "spoke in verse and lived in poetry."" (example extracted from Wikipedia).
biography
An explanatory series of notes or comments; an explanatory essay or treatise on a text. Taking as Opus example "Versos" by Fernando de Herrera, the comments Francisco de Quevedo wrote on his own edition along the text of the poems would form the "commentary".
commentary
An ethnic group; a social group that shares a common and distinctive culture, religion, language, or the like. Taking as Person example the poet "Antonio Enríquez Gómez", his "ethnicity" would be "crypto-Jewish".
Text that narrates an Event, that is, an excerpt of the Redaction. There is at most one possible description for this property. Taking as Opus example the "Poema de Mio Cid", and as Event example the Cid's arrival to Burgos, we find an "eventNarration" in lines 1-64, starting with "De los sos ojos tan fuertemientre llorando".
event Narration
The closing words of the composition (usually, the last verse). There is only one explicit per Redaction. Taking as example the poem "Canary" by Rita Dove, the last verse, "If you can't be free, be a mystery", would be the "explicit".
explicit
It contains a forename, given or baptismal name. Taking as example the poet "Antonio Machado", his "forename" would be "Antonio".
forename
Purpose of the work (e.g. prayer, spell, curse). A Poetic Work or Redaction may have several functions associated. Taking as example the poem "Cantico delle creature" by San Francesco d’Assisi, "function" would be "prayer".
function
It contains a name component used to distinguish otherwise similar names on the basis of the relative ages or generations of the persons named. Taking as example the person "Felipe II", "genName" is "II".
genName
The first line of the work. There is one incipit for each Redaction. Taking as example the "Soledades" by Góngora, the "incipit" is "Pasos de un peregrino son errante".
incipit
In case the identity of current instance of Creator is unknown. Taking as example the creator of "Libro de Alexandre", "isAnonymous" is True because the author is unknown to this day.
is Anonymous
Whether it is a calligram, that is, a text visually arranged in a way that it forms an image associated with the text contents. Taking as example the (calligram) poem "La Colombe poignardée et le Jet d’eau" by Apollinaire, "is Calligram" value is True.
is Calligram
Whether the person under analysis is a fictional character. Taking as example the character "Don Quijote de la Mancha" will have a True value for "is Fictional" property.
is Fictional
Whether the Redaction was composed to be sung. Taking as example the poetic work "Chanson de Roland", "is Song" is True because the work is part of a genre which was sang.
is Song
In case the identity of the current instance of Creator is certainly a wrong attribution. This is applied to the Creator Role associated to a Redaction. Taking as example the poem "Muere lentamente" (by Martha Madeiros) which is erroneously attributed to Pablo Neruda, in the case Neruda is indicated as the author, "is Wrong Attribution" would be True.
is Wrong Attribution
A significant or descriptive word. Usually, a word used as a reference point for finding other words or information. Taking as example the theatre play "Othello" by Shakespeare, one possible "keyword" is "jealousy".
keyword
Language of the text. There might be several languages used in a Poetic Work or Redaction. For example the "language" of "Romancero gitano" by Lorca, is "Spanish" (xsd:string). It could also be represented with the associated langauge code "es" (xsd:language)
language
The arrangement of textual materials (images included) on a page. Taking as example "The Waste Land and Other Poems" by T.S. Eliot, edition by Broadview press, printed in 2011, the "the layout" can be described in the following way: "the text is left aligned, written in one column. Each stanza is followed by a blank space dividing it from the following stanza. The number of lines is displayed by a number marking every five lines which is aligned to the right edge of the page. Every page contains on average 30-40 lines".

This class comprises the sums of concepts which appear in the course of the coherent evolution of an original idea into one or more expressions that are dominated by the original idea. The substance of Work is concepts. A Work may be elaborated by one or more Actors simultaneously or over time. A Work may have members that constitute components of the overall concept or that are alternatives to other members of the work. Members of a work may or may not represent the concept of the Work as a whole; for instance a translation reinterprets the whole, a volume of a trilogy represents a part of the concept. A Work can be either individual or complex. If it is individual its concept is completely realised in a single F22 Self-Contained Expression. If it is complex its concept is embedded in an F15 Complex Work. An F15 Complex Work consists of members that are either F15 Complex Works themselves or F14 Individual Works. The member relationship of Work is based on the members respecting the same concept, and should not be confused with the structural parts of an expression, that might be taken from other work(s). A Work is the product of an intellectual process of one or more persons, yet only indirect evidence about it is at our hands. This can be contextual information such as the existence of an order for a work, reflections of the creators themselves that are documented somewhere, and finally the expressions of the work created. As ideas normally take shape during discussion, elaboration and implementation, it is not reasonable to assume that a work starts with a complete concept. Moreover, it can be very difficult or impossible to define the whole of the concept of a work at some given time. The only objective evidence for such a notion can be based on a stage of expressions at a given time. In this sense, self-contained expressions serve as a kind of "snap-shots" of a work. A Work may aggregate expressions of other works into a new expression. For instance, an anthology of poems is regarded as a work in its own right that makes use of expressions of the individual poems that have been selected and ordered as part of an intellectual process. This does not make the contents of the aggregated expressions part of this work, but only parts of the resulting expression.
Work
This class comprises the sums of concepts which appear in the course of the coherent evolution of an original idea into one or more expressions that are dominated by the original idea.
This class comprises works whose essence is the selection and/or arrangement of expressions of one or more other works. This does not make the contents of the aggregated expressions part of this work, but only part of the resulting expression. F17 Aggregation Work may include additional original parts. An expression of a work may include expressions of other works within it. For instance, an anthology of poems is regarded as a work in its own right that makes use of expressions of the individual poems that have been selected and ordered as part of an intellectual process. A new version of an aggregate work does not make the resulting complex work an aggregate work as well. The inclusion of expressions from a complex work in an aggregation work does not make the aggregation work itself complex.
Aggregation Work
This class comprises the immaterial realisations of individual works at a particular time that are regarded as a complete whole. The quality of wholeness reflects the intention of its creator that this expression should convey the concept of the work. Such a whole can in turn be part of a larger whole. Inherent to the notion of work is the completion of recognisable outcomes of the work. These outcomes, i.e. the Self-Contained Expressions, are regarded as the symbolic equivalents of Individual Works, which form the atoms of a complex work. A Self-Contained Expression may contain expressions or parts of expressions from other work, such as citations or items collected in anthologies. Even though they are incorporated in the Self-Contained Expression, they are not regarded as becoming members of the expressed container work by their inclusion in the expression, but are rather regarded as foreign or referred elements. F22 Self-Contained Expression can be distinguished from F23 Expression Fragment in that an F23 Expression Fragment was not intended by its creator to make sense by itself. Normally creators would characterise an outcome of a work as finished. In other cases, one could recognise an outcome of a work as complete from the elaboration or logical coherence of its content, or if there is any historical knowledge about the creator deliberately or accidentally never finishing (completing) that particular expression. In all those cases, one would regard an expression as self-contained.
Self Contained Expression
This class comprises the immaterial realisations of individual works at a particular time that are regarded as a complete whole.
Any agentive Object , either physical or social. In the context of the POSTDATA ontology network it will mostly refer to organisations or persons
Agent
The CreatorRole class models the role that an agent plays with respect to the creation or authorship of a work. In this sense, it has specific properties that are important for the study of authorship of poetic works. These properties are: penName - It is common for authors to use an alias isAnonymous - In many of the works, especially the older ones, the author is not known and this is an aspect that should be considered. isWrongAttribution - Sometimes, especially in older works as well, attributions of authorship have been made that are not correct, but this fact is considered an important aspect for scholars of the subject. typeofDesignation, which is the type of name or designation used, e.g. pseudonyms, heteronyms, etc.
Creator Role
An abstract work that contains more than one Poetic Work. An Ensemble might be conceived as a collection of works, organized by author, by book song, by book of poems; or as a work mainly written in prose that contains more than one poetic pieces (each one of them being its own Poetic Work). For example, Les fleurs du mal
Ensemble
Something that happens or takes place. It is generally mentioned in the text (Redaction) and represented using isMentionedin property. This class is defined as a subclass of edm:Event. In the future, it may be also defined as a subclass of schema:Event or bibframe:Event, so as to facilitate linking with existing entities already defined according to schema.org or those available in knowledge graphs such as the one from the US Library of Congress.
Event
An ordered list of text units with a given length and indexed elements. Examples of these lists are the list of stanzas and the list of lines, associated to a Redaction.
Ordered Text Unit List
Named collection of people regarded as a single unit. Typical examples include institutions such as ‘UNED’ or ‘the BBC’ and businesses such as ‘Google’ but also racial or ethnic groupings or political factions where these are regarded as forming a single agency such as ‘the Carthaginians’ or ‘the Communists’. This class is defined as a subclass of pdcore:Agent (which is a subclass of edm:Agent) and foaf:Organization, following the design principles used in the EDM ontology. In the future, it may be also defined as a subclass of schema:Organization, so as to facilitate linking with existing entities already defined according to schema.org.
Organisation
A human being regarded as an individual. This person may have existed in real life (e.g., Miguel de Cervantes) or may be fictional (e.g., Don Quijote de la Mancha). This class is defined as a subclass of pdcore:Agent (which is a subclass of edm:Agent) and foaf:Person, following the design principles used in the EDM ontology. In the future, it may be also defined as a subclass of schema:Person, so as to facilitate linking with existing entities already defined according to schema.org
Person
A particular position, point, or area in space; a location This class is defined as a subclass of edm:Place. In the future, it may be also defined as a subclass of schema:Place and geonames:Feature, so as to facilitate linking with existing entities already defined according to schema.org or available in the GeoNames knowledge graph.
Place
Abstract concept of an artistic creation. In the POSTDATA ontology network these creations must be in verse (e.g., poem, play, song). For example, Os Lusíadas by Luis Vaz de Camões; La Commedia by Dante; the poem Ad te deus by an Anonymous author written in between the 7th and 9th centuries.
Poetic Work
Representatives of a work, that is, of a Poetic Work. Each version and edition of a work is its own redaction. Eg.: The palaeographic edition of A solis ortu usque ad occidua preserved in Lat. 1154 (BNF) and its critical edition are two Redaction of the same Poetic Work
Redaction
This class relates a work (e.g., poetic work, redaction, other transmission elements) and an Agent (Person or Organisation), and allows specifying the role that the agent plays in such work (e.g., creator, sponsor, editor)
Role
Text unit of an ordered list. For example, a word, a line or a stanza.
Text Unit
This class comprises people, either individually or in groups, who have the potential to perform intentional actions for which they can be held responsible.

An event is a change "of states in cultural, social or physical systems, regardless of scale, brought about by a series or group of coherent physical, cultural, technological or legal phenomena" (E5 Event in CIDOC CRM) or a "set of coherent phenomena or cultural manifestations bounded in time and space" (E4 Period in CIDOC CRM)
the 2nd World War
the act of painting Mona Lisa
the change of custody of Mona Lisa
Events are identified either by the content provider or by Europeana enrichment at ingestion time
An "extent in space, in particular on the surface of the earth, in the pure sense of physics: independent from temporal phenomena and matter" (CIDOC CRM)
Provided CHO
This class comprises the Cultural Heritage objects that Europeana collects descriptions about.
This class has been mostly motivated by the need to assign a type to the “central node” in the EDM pattern, during the ingestion process, related to the XML expression of EDM at that stage. It was especially intended to fit the cases where edm:PhysicalThing cannot be used as the type of the resource standing for the real-world object (independently of any specific data contributor perspective).
The Organization class represents a kind of Agent corresponding to social institutions such as companies, societies, etc
Organization
The Person class represents people. Something is a Person if it is a person. We don't nitpic about whether they're alive, dead, real, or imaginary. The Person class is a sub-class of the Agent class, since all people are considered 'agents' in FOAF.
