Assuming the previously (brief) description of an Abstract Object, it is possible to map the URL information scheme described earlier onto a SOUR object by making:
| AO Name | scheme://host.domain[:port]/path/filename |
|---|---|
| AO Address | /path/filename |
| AO Type | filename extension (if any) |
| AO Class | scheme + filename extension (if any) |
As expected, an URL provides, just by itself, the minimal information needed for a successful conceptualization [17]. However, if the URL is a HTML text file then some extra information may be added according to its contents (in a way that will be explained in the sections below), otherwise no more information will be attached.
