I have been trying to determine the difference between jcr:title and jcr:description versus metatitle and metadescription (on Metatags tab). My client currently mapa jcr:title and jcr:description to H2 and to "meta property = title" on their pages. However, they notice that there are also these two other properties (metatitle, metadescription) on the Properties>Metatags tab. This is confusing my client's web production team as they don't know if these properties should be populated or not.
