"Name" would be a bit tricky since I'm not sure if we have property
called "name" but for something like date of birth wouldn't it be useful
to link it in the template to
https://www.wikidata.org/wiki/Property:P569 somehow? Is there such
possibility?

In DBpedia we have our own properties and the mappings should use these instead.
Some exceptions exist for very popular vocabularies such as foaf:name but I am not sure if we should allow direct mappings to a wikidata property if an equivalent DBpedia property exists.
In this case it's http://mappings.dbpedia.org/index.php/OntologyProperty:BirthDate
We already have some mappings in place but more are needed for complete coverage
http://mappings.dbpedia.org/index.php?title=Special%3ASearch&search=wikidata&go=Go
 
With identifying properties, however - such as name - I'm not sure if
this could be used.

I agree that general properties such as name are difficult to interpret

Well, in dbpedia it says name is foaf:name, but this could only be
appropriate for humans (and maybe only in specific contexts), for other
entities "name" may have completely different semantics. In Wikidata,
however, properties are generic, so I wonder if it would be possible to
keep context. dbPedia obviously does have context but not sure where it
would be in Wikidata.

We could keep the context in DBpedia and with proper inter-linking do many interesting stuff.

As we discussed yesterday, we could use DBpedia Live and check for updated/stalled/missing values.
For example, if the previous values were the same in DBpedia/Wikipedia & Wikidata and e.g. Wikipedia changes a value we could trigger an update alert, or if a new value such as deathDate in introduced that does not exist in Wikidata.
DBpedia would use dbo:deathDate, but using the link to P570 we could allow an agent to do the check
