This demo is designed to show that it is simple to determine whether a given URL could plausibly be a GS1 Digital Link URI and therefore whether it is worth continuing to process as such. If so, it then interprets the URI and shows what GS1 identifiers are present and their values.
It does this by using plausibleGS1DL.js, which uses the regular expressions included in section 6 of the GS1 Digital Link URI Syntax standard and interpretGS1Scan.js
