Trying to get my head around the options….

OK, so here’s the problem:

An organisation can have multiple names, and it can have multiple URLs…. and sometimes one can identify a straight one-to-one relationship between the two.

For example: Riga Technical University is the english name for Rīgas Tehniskā Universitāte. Being clever, I have identified as the home page (in its native Latvian) and (as the english-language version). I can even associate the URLs as appropriate: the english name links to the english-language pages, and the Latvian name links to the Latvian-language pages.

Life is a tad more complex in other places. For example “Đại học Quốc gia Hồ Chí Minh” can be called either “National University of Ho Chi Minh” or “Ho Chi Minh City Vietnam National University” in english….  yet I have only one URL:

Contrary-wise: EDINA has just one name, but two URLs ( and )

There are, naturally, some unknown number of instances where the name and the URL have not been linked – where the harvesting code was unable to make a “sensible” correlation.

The problem is working out how to model this sometimes-present relationship of many-to-many – in code, in data-returns, and on the screen.
