While building world here goes on, little thing stay unstandardized we can faciliate and easify naming improving congruently/consistently so that new locations read sameway, easy example, searching for "todo" or "to-do" or "to do", or hw subclass naming convention resultindependent, eg listing "to do", "todo", or "to-do" still may vary according to grammar and so, we can however clear whether subclass also shall include brand. example laptops/Dell/DellCpx or laptops/Dell/Cpx one quite good method I fancy is the slugify, that also works for uri and urn, spacereplacing and case insensity, just making sure there won't occur conflicts since slugify is surjective (different may map to same, it's many-to-one or viceversa) Niklas
