  I we use your 'traffic cop/locator' as the link from  guidelines to
techniques.  what is the purpose of the  techniques gateway ?

Gregg says:


>>>1)       In the guidelines themselves, I think it would be nice to have
the links, but have the big long sentences would make it unduly long. How
about if after every >>>item in the guidelines, we just simply have 2
one-word links. Perhaps they could be in square brackets to set them off but
they would be in the same line as >>>the guidelines so they wouldn't use up
an extra vertical line of space. For example:


>>>[Checklist] [Techniques] 


I like that.



>>>2)       Traffic cop really does cause people problems and also sounds
like Bobby, which is not let that function would be


>>>I don't have a good final suggestion but some ideas to get us thinking.


>>>-          Locator

>>>-          Technique Locator

>>>-          Customizer



Yeah, I knew early on that the name "Traffic Cop" wasn't a keeper. I was
just thinking of it as a code name until we had a better name. But I love
the concept and basic design of the "whatever we call it."  




>>>>On the second illustration where you show the two flow pads off of the
guidelines, the first box is the guidelines and the last box at the bottom
is either the >>>techniques or the checklists. Between them are two boxes
which have a description but not a name. Aren't these really the techniques
gateway document and the >>>checklist gateway document? If they are, we
might just label those boxes on the diagram with those names and then put
the function in parenthesis underneath them.


I was going to call these two boxes "mini cops" but thought I better leave
them unnamed for obvious reasons.

I wasn't thinking of those boxes as the current "Technique Gateway" document
which currently contain the "Technology Independent Techniques". I was
thinking of them as what you call above a "Locator" .  The way into the
Techniques from the Guidelines (the left middle box) would be something like
this www.eramp.com/david/traffic_cop_from_guidelines.htm  The way into the
Checklists from the Guidelines (the right middle box of the 2nd diagram)
would be something like this


Perhaps on one of our Thursday calls I should explain these use cases that
have grown out our Wed Techniques calls.

Hi Becky


I made the adjustment for Use Case persona Andy's printing from the
Checklist (not the Techniques). 

I've posted these use cases to
www.eramp.com/david/becky_use_cases.htm     <http://
The models for the Traffic Cop and navigation paths through the documents
are at www.eramp.com/david/    <http:// www.eramp.com/david/>


I also made a temporary Checklist gateway that will serve as a placeholder
until I understand all the checklists and how the will look and work
together. It is here. Use Case persona Jessica would have sent this URL

Thanks very much to David for wading through my use cases and creating the
drawings!  I think his diagram in the posting from
http://lists.w3.org/Archives/Public/w3c-wai-gl/2004AprJun/0333.html captures
everything that these use cases require - I just needed to create a "real
world" scenario to wrap my head around them better!   I also don't fully
understand the checklists and how they will be organized.  I liked his
example at  <http://www.eramp.com/david/benshtmlchecklist.htm>
http://www.eramp.com/david/benshtmlchecklist.htm.  I also envision one page
that is able to encapsulate the entire checklist for a specific technology
but that may be too complicated.     

I agree that it is probably too complicated to add all the checklist links
to the traffic cop but it would be a good idea to add a link to the
checklist gateway from there.  I would like to see a link to the checklist
gateway in the cell/row  for each guideline.  It seems like overkill since
it will be the same link in each cell but a person may enter the traffic cop
in the middle and not find a checklist gateway link at the top or bottom of
the page.     Also, do you think it makes sense to add a link to the
checklist from the success criteria page?  This will allow direct access to
a checklist with just one hop from the traffic cop.   That may be too
complicated to maintain, though, but I think it would be helpful.   

In the Jessica example you have: 
1) The first link she sends is here: 

This actually takes you to a checklist gateway for a particularly guideline.
I was envisioning a Checklist Gateway that is not guideline specific and
allows you to select a technology.  I then assumed that Andy would pick the
HTML or CSS set of checklists.  But, this gets back to how the checklists
are organized - is it possible to have all of the checklist for one
technology in the same document?  One other minor nit in the diagram is that
I expected Andy to print an HTML checklist.  You have the printing from the
techniques (which is also a good idea) branch.  I just wanted to include
printing so we would think about it when we designed the checklist page.

[TECH] use cases diagrammed




My action item was to make drawings and comments on Becky's use cases.  My
drawings are simple box diagrams so that "lay people" can easily understand
them. They are based on UML principles but not strict UML (to avoid visual
jargon that might not be understood by all and inaccessible). I've posted
these use cases to  <http://www.eramp.com/david/becky_use_cases.htm>
