Triplification failure

I was trying to add the triplify add-on for Wordpress to this blog. Unfortunately things didn’t go quite according to plan. Firstly, the documentation on the website is not very detailed particularly with regards to installation instructions. The instructions contained in the readme file in the download package were more helpful.

Secondly, there is no mention of the add-on only being compatible with PHP 5.1.x and higher. The problem occurs in the pdo package that is installed as standard in PHP 5 but not PHP4. This package is used to manage database connections to a range of databases including MySQL and PostgreSQL. After hunting down a PHP4 compatable version of PDO i thought things might fit together. However, after hacking around with a PHP4 PDO class i started getting curious hebrew error messages:

PHP Parse error: parse error, unexpected T_PAAMAYIM_NEKUDOTAYIM, expecting ',' or ';' in /home/.../triplify/PDOStatement_mysql.class.php on line 42


‘Paamayim Nekudotayim’ as it turns out is Hebrew for ‘double colon’, an error message left by PHP’s israeli authors.

So my attempt to add this blog to the Linked Data world were unsuccessful. It is also hard to upgrade to PHP5.2 since uses Red Hat Linux Enterprise and there is currently no rpm available for this distro. At least the SIOC plugin seems to be working and should be useful if i decide to manually export the data of this blog as Linked Data.
