SPARQL Typographical and Syntax Conventions
The following table describes the conventions used in describing the syntax of various SPARQL commands, clauses, and other statement options.
| Convention | Description |
|---|---|
| CAPS | Although SPARQL is case-insensitive, SPARQL keywords in this section are written in uppercase for readability. |
| Italics | Terms in italics are placeholder values that you replace in the query. |
| [ element ] | Indicates an optional clause. |
| | | Means OR. Indicates that you can use one or more of the specified options. |
| ^ | Means exclusive OR (XOR). Indicates that you can only choose one of the specified options. |
| <> |
Representation of subject or predicate values based on an IRI or URI specification. AnzoGraph places no special restrictions on URIs, only that you place the text between < > characters, for example, <sales>. |
| << >> |
Specifies a relationship property in a triple store, with the triple wrapped between the double angle bracket characters, << triple >>, with the property URI and property value specified at the end of the triple, that is: << <subject> <predicate> <object> >> <property_URI> <property_value> |
