 Note that a blank-space must separate the subject, from the predicate, from the object, and that a "period" completes the triple. This is essentially a valid RDF triple, although of course there would need to be some additional information associated with it, such as an RDF namespace declaration:

+1. Be sure you have used the right classes, properties, or vocabularies for your annotation components
   1. Become familiar with the vocabularies in your annotation, especially definitions and relationships 
   1. Check with your community for specific recommendations on annotations at different levels 
 1. In additionalMetadata, don't combine `<annotations>` with more than one `<describes>` element. EML allows 1:many `<describes>` elements in one additionalMetadata section. So if you have 2 `<describes>` and 2 `<annotations>`, you will have 4 RDF statements. Make sure they are all true, and if not, break them up
