Fellow Magnolians! Last days, we are facing an i...nteresting issue in our projects, namely a problem with the (Facebook's) Open Graph (OG) tags[1]. Our clients want to embed better Social Media binding into their pages, and while Twitter is fairly easy, Facebook is a tough proposition.
The problem is, that OG Tags must be embedded into the <header> part of the page, because they are actually <meta> tags, and they must be present in the HTTP response body, not set later using some Javascript. But in the moment of rendering the html header, I do not know, what content is going to be rendered, do I? Well, if the page is "static", I could extend the Page Properties dialog, put the required info there, and use it the same way as the page title etc. are displayed. The headache starts when I have a page with dynamic content, let's say a product catalog. Then I have a page, e.g. http://my.customer.com/product.html which contains a Product component, rendering a product information according to a product code provided as request parameter. With a bit virtualURIMapping, I could have nice URLs like http://my.customer.com/product/productCode1, http://my.customer.com/product/productCode2 etc. Our client wants, that the OG tags in the page are set according to the displayed product, so if someone shares the page to Facebook (via pasting the URL, not using the "Share" button eventually embedded into the page), the proper product information and picture will be displayed in that FB post. So far, we've come to the conclusion, that we have to create a special PageModel for such pages, search the page's non-page subnodes, if the contain a definition of a concerned component, instantiate and execute the component, get the OG tag values (provided that our component already supports them), and use them in rendering the page header. To be honest, I don't like the solution at all, but does any of you have a better idea? Best regards, Jozef.
