3.5 AO Members

In a similar way, the source text of the URL currently being accessed can also be used to extract AO member information. Each hyperlink to a local file will be identified as a member of the AO that maps the current URL. Possible references include:

Hyperlink references

- e.g. <A HREF = ``FILE''>...</A>;

Image references

- e.g. <IMG SRC = ``FILE''>...</IMG>;

Embedded references

- e.g. <EMBED SRC = ``FILE''>.

All these references will create member links identified by the label ``Member Of''. In the running example above, references 1 and 2 from the previous section,

• <IMG ALIGN=MIDDLE SRC="/IMI/imi2-ing-interlace.gif">
• <A HREF="http://www.di.uminho.pt/english-um.html">

will produce AOs

AO Name	http://www.di.uminho.pt/IMI/imi2-ing-interlace.gif
AO Address	/IMI/imi2-ing-interlace.gif
AO Type	GIF
AO Class	HTTPGIF
Domain0	www
Domain1	di
Domain2	uminho
Domain3	pt

and

AO Name	http://www.di.uminho.pt/english-um.html
AO Address	/english-um.html
AO Type	HTML
AO Class	HTTPHTML
Domain0	www
Domain1	di
Domain2	uminho
Domain3	pt

Finally, these two AOs will produce the member links:

• http://www.di.uminho.pt/IMI/imi2-ing-interlace.gif
• http://www.di.uminho.pt/english-um.html

which will become part of the conceptualization profile of the current URL. Figure 4 shows the RM's Zoom In graphical functionality [19] operating on URL ``http://www.di.uminho.pt/cnw3.html''.
