Topic Map conversion of YSO
YSO is the Finnish General Upper Ontology based on the Finnish General Thesaurus maintained by The National Library of Finland. The Finnish General Thesaurus was converted to YSO by Semantic Computing Research Group (SeCo) during FinnONTO project. SeCo also hosts YSO in their National Finnish Ontology Service ONKI. Detailed description of YSO is available at Tietolinja magazine 1/2007 (in Finnish). YSO is an acronym of words Yleinen Suomalainen Ontologia. YSO contains ca. 20 000 concepts.
Topic Map conversion of YSO is based on RDF dump kindly provided by the SeCo team. Topic Map YSO was created using Wandora's RDF import feature. Machine translated YSO was processed manually to fix topic names and associations. Topic Map conversion is not identical to RDF version. Differences are discussed below.

Conversion details
Below is a screenshot of Wandora with Topic Map conversion of YSO. Wandora's topic panel has todellisuus topic (reality in Finnish) open. Topic has variant name in Swedish and English. Topic plays also a role in Associative Relation and Related-Term associations. Term's domain and superclass have also been specified with equivalent associations.
In general each YSO term topic is an instance of topic term (yso). YSO term has a base name of equivalent Finnish word and contains Finnish, Swedish, and English variant names. In some cases English variant is missing. Some terms also contain alternative labels as altLabel (yso) occurrences. Term may also contain short description as a comment (rdfs) occurrence.
Each term topic has two subject identifiers. First identifier refers to term's YSO id. Second refers to equivalent YSA id i.e. id of term in Finnish General Thesaurus. For example, previous screenshot had a topic with subject identifiers

Term topic may contain associations:
- Superclass-Subclass associations specify standard sub-superclass relations between terms.Root node of Superclass-Subclass associations is topic yso-käsitteet. Subclasses of root node are muuttuva, pysyvä, and abstrakti. Graph below views Superclass-Subclass associations of topic ilmiöt (phenomena in English). Dark blue arrows and texts were added in PhotoShop.
- Associative Relation associations specify a general relation between two terms. It looks like most Associative Relation associations have a symmetric duplicate where players have been switched. This duplicates the amount of Associative Relation associations.
- Broader-Narrower associations express the fact that a term is some way more general than another.
- Homonym associations link terms with identical names but different meaning. Identical base names merge in topic maps and base names contain additional number to distinguish different term topics. For example osakeyhtiöt has a homonym with base name osakeyhtiöt_2.
- Meronym associations specify part-whole relations between term topics.
- Related-Term associations specify a general relation between two terms. It looks like these associations are similar to Associative Relation associations. However, association groups are not identical and they have been left separate.
- Term-Domain associations specify term's domain. YSO contains 61 different domains. Domains are instances of domain (yso) topic.
Limitations
- Original YSO RDF(S) contains separate RDF resources for YSA terms and YSO concepts. These two resources have been merged in Topic Map conversion of YSO. YSO Topic Map contains single topic for one YSA term and YSO concept pair. As a consequence each term topic has two subject identifiers, one referring the term and one referring the concept.
