doug: I think it is good to come from both angles - doesn't see a big
difference between the staw man taxonomy
... chart type taxonomy has more properties - roles, category, values,
parent applies to...
... describing axis


fesch: issues on "aria-axisdimension"


doug: may have different level of abstractions - depending on whether we
have well known charts or not


jw: aria defines a ontology which is a conceptional hierarchy, and we may
have very specific kind some may instantiate and some more abstract
... lets think of this a hierarchy


doug: in aria 1 you can't instantiate an higher level abstract role, we
will allow instantiating higher level roles


rich: discussion on aria-axisdimension can be a attribute...
... don't need to include role in the attribute name -ie aria-axisdimension
could be dimension


doug: thinks the long name aria-axisdimension makes it easier for software
to read it


fesch: discussion on axis vs dimensions


doug: lets delay detailed discussion on axis vs dimension
... described legends
... described dataset
... might have multiple datasets in a chart


fred: does a dataset = a table?


amelia: a dataset could be a table and rows are a data point


doug: data set may not = a table


amelia: likes term facet


doug: tried to limit aria roles and attributes to make it easy to put in
the SVG
... tried to map to objects in the SVG


rs: doug is saying axis is an important container... affects the mapping
specification which we need to consider


doug: advantage is you must be explicit so the screen reader can extract
the information


rs: each role has a defined name computation strategy - two ways to
approach it, name from content... we don't want name from context


doug: mentions different facets, x, y, legend, size.... might have
invisible facet in there


rs: what is strategy on axis labels?


doug: strategy varies
... for value min and value max might be better strategy than worrying
about axis ticks
... should have document on interaction modes


rs: graphs may be scrollable....
... do you think scrollable interaction is valuable or not?


doug: yes


fesch: defender view vs scrollable, zoomable - scrollable, zoomable get
whole chart, defender view - get a window - as a entire chart


amelia: likes strategy of focusing on mappings... will work on strawmen and
keeping stuff general
