| ==== 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 |
