Having another look around schema.org; I noticed that something very similar to Richard's identifier proposal already exists in the health/medical extensions to schema.org. [1] It is used for expressing the medical code for an entity in microdata. Examples can be found at [2], [3] and [4]. I paste part of [4] into the mail: <span itemprop="about" itemscope itemtype="http://schema.org/Drug"> <span itemprop="name">Metformin</span> <span itemprop="code" itemscope itemtype="http://schema.org/MedicalCode" itemid="http://www.ncbi.nlm.nih.gov/mesh/D02.078.370.141.450"> <!-- Note: use of itemid is not mandatory, but recommended when an external enumeration is available --> <meta itemprop="code" content="D02.078.370.141.450"/> <meta itemprop="codingSystem" content="MeSH"/> </span> Some of Richard's proposed properties can be translated to this approach: name --> code identifier --> code inStandard --> codingSystem Of course, this couldn't be used out of the box and the naming ('code' vs. 'identifier') isn't the same. But, generally I don't think that there is a significant difference between a code for a disease or a drug and an identifier for a CreativeWork. I assume, it would be a good approach to pick up the medical approach and extend it to other domains than to come up with a new proposal. (I also put this onto the wiki page at [5].)
