0.5.0

• Update to skosprovider 0.6.0
• Minor BC break: A skosprovider_sqlalchemy.models.Language that gets cast to a string, now returns the language's ID (the IANA language code),as opposed to the language's description it would previously return.
• Minor BC break: The URI attribute has been made required for a skosprovider_sqlalchemy.models.ConceptScheme. Before it was optional, but it probably would have caused problems with skosprovider anyway.
• Due to the update to skosprovider 0.6.0, a new field markup, was added to a skosprovider_sqlalchemy.models.Note. When upgrading from a previous version of skosprovider_sqlalchemy, any databases created in that previous verions will need to be updated as well. Please add a field called markup to the note table.
• Inline with the skosprovider 0.6.0 update, a languages attribute was added to skosprovider_sqlalchemy.models.ConceptScheme. When upgrading from a previous version of skosprovider_sqlalchemy, any databases created with that previous verions will need to be updated as well. Please add a table called conceptscheme_language with fields conceptscheme_id and language_id. (#18)
• To comply with the skosprovider 0.6.0 update, the sources attribute was added to skosprovider_sqlalchemy.models.Conceptscheme, skosprovider_sqlalchemy.models.Concept and skosprovider_sqlalchemy.models.Collection. When upgrading from a previous version of skosprovider_sqlalchemy, any databases created with that previous verions will need to be updated as well. Please add a table source with fields id, citation and markup, a table concept_source with fields concept_id and source_id and a table conceptscheme_source with fields conceptscheme_id and source_id.
• All methodes that return a list have been modified in line with skosprovider 0.6.0 to support sorting. Sorting is possible on id, uri, label and sortlabel. The last two are language dependent. The sortlabel allows custom sorting of concepts. This can be used to eg. sort concepts representing chronological periods in chronological in stead of alphabetical order. (#20)
• To comply with the skosprovider 0.6.0 update, the deprecated skosprovider_sqlalchemy.providers.SQLAlchemyProvider.expand_conceptwas removed.
• When importing a provider, check if the languages that are being used in the provider are already in our database. If not, validate them and add them to the database. In the past the entire import would fail if not all languages had previously been added to the database. (#14)
• When importing a provider, try to import as much information as possible about the concept_scheme that's attached to the provider. (#19)
• When querying for indvidual an conceptscheme or concept, use joinedload to reduce the number of queries needed to collect everything. (#15)
• Deprecated the :func:skosprovider_sqlalchemy.models.label function. Please use skosprovider.skos.label from now once, since this function can now operate on both skosprovider.skos.Label and skosprovider_sqlalchemy.models.Label instances. This was the reason for the BC break in this release.
