. . . . "We should think about mechanisms to harmonize and monitor the use of identifiers in nanopublications. For instance, Digital Object Identifiers (DOIs) can be referred to in several ways: preceded (or not) by \"doi\" or \"DOI\" (with or without a colon), as a URL or a string. Further options: with https or http, with the deprecated legacy \"dx\" prefix or not, case-normalized (up or down) or not. For Crossref DOIs, guidelines are available, and there are other DOIs too. There might be nanopublications (particularly legacy ones) that do not follow any guidelines but Shape Expressions (ShEx) might assist in monitoring / filtering variation." . . . .
