Just released, the new WPSSO Google Merchant Feed add-on retrieves product information from WPSSO Core Premium and provides maintenance free XML feeds for each WordPress language (aka locale).

There are no add-on settings to configure — the WPSSO Google Merchant Feed add-on automatically retrieves all product information in the language (aka locale) requested.

A supported e-commerce plugin, like WooCommerce or Easy Digital Downloads, is suggested but not required — the WPSSO Google Merchant Feed add-on can also retrieve custom product information entered in the WordPress editor Document SSO metabox. WooCommerce variations and additional WooCommerce product attributes are fully supported.

I’ve found a few snippets of PHP code to read XMP / XML meta data from an image file, but none that I would call very robust or efficient. I ended up writing my own for Underwater Focus, and I’m quite pleased with the result. In fact, after adding support for a shortcode, I packaged it as an Adobe XMP plugin for WordPress.

The first part of using XMP meta data is reading the XMP information from the image. I’ve seen a few solutions that read the whole file into memory, and others that read-in just a small part. If the XMP / XML contains a lot of information, that small part may be incomplete. And each time the XMP meta data is required, the original (and sometimes quite large) image file must be re-read. Since the XMP doesn’t change unless the original image is updated, there’s no reason to keep re-reading the same large file time and time again.
