RiC-O v1.0-beta

This version, although it should only be used for testing purposes, is very close to the RiC-O 1.0 version, which will be released by the beginning of December 2023.

Here are the main changes made by this version compared to version 0.2 released in February 2021:

• fixed various bugs; removed some unnecessary formal declarations (#46);
• making RiC-O fully compliant with version 1.0-beta of RiC-CM: see the issue relating to the modification of the ontology as concerns the modeling of dates (#62), the issue #45, and the related ones, #73, #74, #75;
• creation of transitive object properties, subproperties of followsOrFollows, hasOrHadPart, hasOrHadSubordinate, and of their inverse properties (#41);
• addition of some properties to respond to user requests: isAgentAssociatedWithPlace, isOrWasEmployerOf; wasMergedInto and wasSplitInto (#53), hasDeathPlace and hasBirthPlace (#34), hasOrHadAnalogueInstantiation and hasOrHadDigitalInstantiation (#60), and of their inverse properties;
• rolification of the n-ary Relation classes (see #67);
• addition of labels (rdfs:label) in French for all classes and properties, and in Spanish for classes, datatype properties and 305 object properties out of 400 (#43)
• update of metadata and the introduction of the ontology (#76).
  Each of the modifications made was documented by a skos:changeNote annotation added to the specification of the modified component.
  In addition, an HTML page allowing anyone with an internet browser to easily consult the contents of the OWL file has been provided.

A big "thank you" to all the people who, outside the ICA/EGAD group, contributed to the development of this version, through their requests, their comments, their advice or their help during the translation of the labels.
