I am preparing a new version of solidTiddlywiki that use turtle files to store the tiddler.  
I would like some comment on the choices I made for the vocabularies and ontologies to convert the tiddlywiki’s references to RDF.

```
this.ontology = {
	"dc":"http://purl.org/dc/elements/1.1/",
	"dcterms":"http://purl.org/dc/terms/",
	"schema":"https://schema.org/",
	"ex":"http://example.org/vocab#" // "ex" is needed : used as default tiddlywiki ontology
}

this.prefix = "";
Object.entries(this.ontology).forEach(
 ([key, value]) => {this.prefix = this.prefix+"\n@prefix "+key+": <"+value+"> ."}
)

// subject
this.subject = "\n\n<this>" ;
	
// tidlerKeys to turtle predicate
this.tiddlerKeys = {
	"created":"schema:dateCreated",
	"creator":"schema:creator",
	"text":"schema:text",
	"title":"dc:title",
	"type":"dc:type",
	"tags":"schema:keywords",
	"modified":"schema:dateModified",
	"modifier":"schema:contributor",
	"_canonical_uri":"schema:url",
	"draft.of":"ex:draft_of", // dot not allowed in RDF vocab
	"draft.title":"ex:draft_title"} // dot not allowed in RDF vocab
```
