SUBROUTINES ^

new

Create a SADI::Utils reference; useless since the methods in this module can be called statically.

find_file

Try to locate a file whose name is created from the $default_start and all elements of @names. If it does not exist, try to replace the $default_start by elements of @INC (one by one). If neither of them points to an existing file, go back and return the $default_start and all elements of @names (even - as we know now - such file does not exist).

There are two or more arguments: $default_start and @names.

getHttpRequestByURL

returns a scalar of text obtained from the url or dies if there was no success

empty_rdf

returns a string of RDF that represents a syntactically correct RDF file

trim

trims whitespace from the begining and end of a string

LSRNize

Augments LSRN records with ('has attribute' some Class and ('has value' some String))

Input: $class: the LSRN record (an OWL::Data::OWL::Class object), $id: a literal representation of the identifier

Output: $class with the following added to it:

<$class, SIO_000008, Y> <Y, rdf:type, $identifier> <Y, SIO_000300, $id>

This subroutine assumes that it can load the appropriate LSRN record as a Perl module (i.e. you have generated OWL2Perl classes for the LSRN record)

unLSRNize

Extracts the LSRN records literal value from the RDF model

Input: $input: the LSRN record RDF::Core::Resource, $core: a SADI::RDF::Core object

Output: a scalar representing the LSRN records literal value or undef if it did not exist.
