Catalogs provide a means to populate and administer translations, help text and alias values at the WebApp and page levels.
When phrases on a page are translated, the platform searches through all catalogs assigned to the page. A translation is attempted to be made at the highest level catalog. If a match is not found, the next level catalog is searched until a phrase translation match is found.
It is recommended to translate phrases at the most generic level appropriate. The higher the level the phase is translated, the more useful the translation will be. A phrase translated at the Catalog (WebApp) level can be reused by many applications and many pages. A phrase translated at the page level is only good for that single page.
There are cases where a phrase has a unique meaning on a page, different from its usual meaning, and should be translated at the page level. However, page-level translation should be the exception to the rule.
