The text was: [ By defining a WebID to be a hash-based we put a lot of semantics into a single character where the most important parts are that an entity is described in a standardized way. Two identical => descriptions <= of a real world entity are treated differently if webid.toString().indexOf("#") is -1 or > 0. That what's interesting for the verifier is not the uri-string, but the description of an entity. In other words a verifier must judge the graph not (only) by the triples it contains, but also by a certain character in the subject's uri. ] Once again, we ALWAYS introspect on a string to determine next steps. It may be one character but the : after the http is also a case of introspection, based on the URI spec. HTTP has its regex too for defining things such as domain, port and fragment. Yes the triples in a document are important but so is the URL. > > > Henry > > > > > wkr turnguard > > > > -- > > | Jürgen Jakobitsch, > > | Software Developer > > | Semantic Web Company GmbH > > | Mariahilfer Straße 70 / Neubaugasse 1, Top 8 > > | A - 1070 Wien, Austria > > | Mob +43 676 62 12 710 | Fax +43.1.402 12 35 - 22 > > > > COMPANY INFORMATION > > | web : http://www.semantic-web.at/ > > | foaf : http://company.semantic-web.at/person/juergen_jakobitsch > > PERSONAL INFORMATION > > | web : http://www.turnguard.com > > | foaf : http://www.turnguard.com/turnguard > > | g+ : https://plus.google.com/111233759991616358206/posts > > | skype : jakobitsch-punkt > > | xmlns:tg = "http://www.turnguard.com/turnguard#" > > > > > > Social Web Architect > http://bblfish.net/ > >
