| ==== The Grammars |
| See Archive for old, historical material. |
| |
| master.jj - Template for SPARQL and ARQ |
| cpp input to produce sparql.jj or arq.jj |
| |
| sparql_11.jj - The SPARQL working group syntax |
| This should be exactly the grammar in the SPARQL rec. |
| Generates org.apache.jena.query.parser.sparql_11.SPARQLParser |
| |
| arq.jj - The native query language of the query engine |
| Generates org.apache.jena.query.parser.arq.ARQParser |
| |
| |
| sparql_10.jj - SPARQL 1.0, but updated to match internal chnages in ARQ. |
| This should produce the grammar in the SPARQ 1.0/DAWG rec. |
| Generates org.apache.jena.query.parser.sparql_10.SPARQLParser |
| |
| Archive/sparql_10-REC.jj is original for the SPARQL 1.0 specification. |
| |
| Archive/rdql-arq.jjt |
| RDQL for the ARQ query engine. |
| Generates org.apache.jena.query.parser.rdql.RDQLParser |
| |
| ==== Making the parsers |
| |
| See "grammar" |
| Note this runs cpp over master.jj to produce arq.jj or sparql.jj |
| |
| ==== Making the HTML |
| |
| sparql_N.txt is produced by "grammar", used to make HTML. |
| We don't use jjdoc to produce HTML but instead get jjdoc to produce |
| its text form and process that, toegther with a hand-managed |
| token.txt file. |
| |
| == Tokens |
| |
| Run "jj2tokens sparql_11.jj > tokens.txt" to get a first pass at a tokens file. |
| Manually tidy, noting which to inline |
| |
| Produce HTML suiatble for inclusion in the SPARQL recomendations. |
| Includes some hand-craft tidying up. |
| jj2html arq.txt tokens.txt |
