If you're going to go this route, you may also want to think about uri component encoding (JavaScript: encodeURIComponent) the individual identifier components. Then you can use a generic query string parser library to get the components from the string, and can also efficiently embed the identifier as part of the query string in the url.

Thanks Gregor! I must say I really like this idea for our short term solution! Will discuss this with my team.
Best,

On the original question: my preference when creating an identifier for the triplet would be to be transparent, and create the identifer with the dwc terms embedded,
i.e. use
institutionCode=BGBM&collectionCode=xxx&catalogNumber=289742874239872
as the "self-coined" identifier string. While "&" may not be unique, the delimiter
&collectionCode=
is very likely so. And it is transparent, self-documenting what is going on (and I do not mean that people need to parse it - which they could in either case)

Hi everyone,
I guess there might have been some discussions about proper delimiter characters in the past that I have missed.
In several projects, first of all in GGBN (Global Genome Biodiversity Network, http://www.ggbn.org), there is a need for making a decision now. We need to reference between different records and databases and within Darwin Core we want to use the relatedResourceID to do so.
During our GGBN workshop at TDWG last year we agreed on concatenating the traditional triple ID (Catalogue Number, Collection Code, Institution Code) and add further parameters if required too (e.g. GUID, access point). We have checked those parameters and can definitely not use a single character as delimiter.
So my question to you is, if there are already some suggestions on using two characters together as delimiters. It would be great if we could find a solution more than one community could agree on.
Otherwise I would like to open the discussion and suggest "\", "||", "|", "§|", "§§", or "\§".
Best wishes,
Gabi
