Scope
Mapping GFF2RDF (proposal)
The following table is in a very inmature state...
| GFF Element | RDF (XML) | Description |
| Column 1: "seqid" | <gff:seqid rdf:about="#ctg123"> | ? |
| Column 2: "source" | <gff:source>1000</gff:source> | ? |
| Column 3: "type" | <gff:type rdf:about="#SO:0000704"> | ? |
| Column 4: "start" | <gff:start>1000</gff:start> | ? |
| Column 5: "end" | <gff:stop>9000</gff:stop> | ? |
| Column 6: "score" | <gff:score>5.8e-42</gff:score> | ? |
| Column 7: "strand" | <gff:strand>+</gff:strand> | ? |
| Column 8: "phase" | <gff:phase>.</gff:phase> | ? |
| Column 9: "attributes" | <gff:attributes><rdf:Description>...</rdf:Description></gff:attributes> | ? |
Tools
- GFF to OWL (Source code not available yet?)
Discussion
- application to general genomic features (BED, etc)?
- Genomic coordinate system (0-based / 1-based)
- Dasty?
