| 31 | * \section sec_main_intro Introduction
|
|---|
| 32 | *
|
|---|
| 33 | * \libname provides an implementation of the \c RDF \c API and
|
|---|
| 34 | * the \c RDFa \c API as described in the according specifications of the W3C.
|
|---|
| 35 | * Support for the \c RDF \c Interfaces specification will be included
|
|---|
| 36 | * in a forthcoming version.
|
|---|
| 37 | *
|
|---|
| 38 | * For the following reasons certain classes, methods etc. are not or differently
|
|---|
| 39 | * implemented:
|
|---|
| 40 | * - this library is not an implementation for usage in a Browser-based environment,
|
|---|
| 41 | * so certain classes and methods are not required
|
|---|
| 42 | * - differences between the otherwise very similar \c RDF \c API and the
|
|---|
| 43 | * \c RDFa \c API lead to slight incompatibility with either specification
|
|---|
| 44 | * - for convenience, some mon-standard classes and methods have been implemented
|
|---|
| 45 | * on top of the \c RDF \c API and \c RDFa \c API specifications, some of them
|
|---|
| 46 | * have been taken from the \c RDF \c Interfaces specification.
|
|---|
| 47 | * All of these additions are marked accordingly within the documentation.
|
|---|
| 48 | *
|
|---|
| 49 | * See the section \htmllink{page_appendix_w3cspecs.html,W3C Specifications Overview and Library Compatibility}
|
|---|
| 50 | * for more information.

|
|---|
| 52 | * \section sec_main_prereq Prerequisites
|
|---|
| 53 | *
|
|---|
| 54 | * For parsing and serializing RDF data, this library requires the \c ARC2 library. \n
|
|---|
| 55 | * Download from \htmllinkext{https://github.com/semsol/arc2/downloads}
|
|---|
| 56 | *
|
|---|
| 57 | * \note For usage under Windows operating systems,
|
|---|
| 58 | * \htmllink{page_appendix_arc2_patch.html, a patch is required} to be able to read files from
|
|---|
| 59 | * the local filesystem.
|
|---|
| 60 | *
|
|---|
| 61 | * \section sec_main_options Options
|
|---|
| 62 | *
|
|---|
| 63 | * See the following sections for further options with using \libname:
|
|---|
| 64 | *
|
|---|
| 65 | * - \htmllink{page_option_fdebug.html,Using fDebug to log debug event messages}
|
|---|
| 66 | * - \htmllink{page_option_unittest.html,Executing RDFint.PHP unittests}
|
|---|
| 67 | * - \htmllink{page_option_doxygen.html,Generating the RDFint.PHP online help}
|
|---|
| 68 | *
|
|---|
| 69 | * \section sec_main_config Configuration
|
|---|
| 70 | *
|
|---|
| 71 | * To setup \libname, the following environment variables must be defined:
|
|---|
| 72 | *
|
|---|
| 73 | * \desctable
|
|---|
| 74 | * \desc{<strong>Environment variable</strong>,<strong>Value</strong>}
|
|---|
| 75 | * \desc{\c PHP_LIBROOT_RDFINT,Root directory of \libname - contains \c rdfa.php}
|
|---|
| 76 | * \desc{\c PHP_LIBROOT_ARC2,Root directory of \c ARC2 - contains \c ARC2.php}
|
|---|
| 77 | * \enddesctable
|
|---|
| 78 | *
|
|---|
| 79 | * \note Also under Windows operating systems, pathnames \c MAY \c NOT contain backslashes!
|
|---|
| 80 | * Instead slashes \c MUST be used.
|
|---|
