TL;DR: The CDA R2 model is richly expressive, enabling the formal representation of clinical statements such that they can be interpreted and acted upon by a computer, and offers a low bar for adoption.

TL;DR: The approach and objectives of the HL7 CDA are presented, along with a technical overview of the standard, which is a document markup standard that specifies the structure and semantics of clinical documents.

TL;DR: Eleven specific areas that represent relevant barriers to the interoperability of C-CDA documents are identified and point to several practical opportunities to improve C- CDA document quality and exchange in the coming years.

TL;DR: It is demonstrated that electronic patient data can be reused for prospective multicenter clinical research and patient care, and demonstrates a need for further development of therapeutic area standards that can facilitate researcher use of healthcare data.

TL;DR: The objective in this paper is to take a step back, and consider what semantic interoperability means, assess whether or not it has been achieved, and, if not, determine what concrete next steps can be taken to get closer.
