Hi, I want to create a Lucene analyzer for RDF nodes. RDF nodes can have multiple types (uri, bnode, plain literal, plain literal with language, typed literal with datatype). While analyzing the term, I want to create a RDFNodeTypeAttribute, LanguageAttribute and DatatypeAttribute to store respectively the type of RDF node, the language of the literal and the datatype attribute. My question is how these attributes can be stored in Lucene index. Do I have to write a custom Codecs ? Do I have to use the PayloadAttribute ? How can I leverage these attributes once stored in the index for my search ?
