General
This is an architectural drawing tool. It
reads/saves information in xml, gml or ACME
format. It renders an architecture as a 2D graph
and uses one of several algorithms to perform
automatic layout. Each node or edge may have an
underlying representation which itself is a
graph. Each node or edge in the graph may also
have text properties associated with it. It
should be possible to view these properties from
within the program. Properties have the format
name-type-value.

Story 0
I want to start the application and see a splash
screen with the program name, and GT logo. After
the application loads, I should be able to either
load in an architecture or begin creating one.

Panes..) Create Splashscreen.

Story 1
I want to draw a node on the screen and assign
the desired properties to it. Nodes are drawn as
rectangles with the component name inside the
node. Connections for edges are made at ports
which are shown as circles on the perimeter.

Story 2
I want to draw an edge between any two nodes and
assign properties to that edge. Edges connect to
nodes via ports. Once an edge is connected, any
movement of the node moves the corresponding
edges (they stay connected).

detailed representation in another window. (Also
known as drill-down).

I want to import architectures defined in XML
(xADL) and correctly draw them and their
corresponding properties. See http//www.isr.uci.
edu/edashofy/papers/wicsa2001.pdf and
http//www.isr.uci.edu/projects/xarchuci/
TASKS Interface with XML Library
Read components and create nodes
Associate properties Read
connectors and create edges
Associate properties Create
sub-graphs as necessary

Story 6
I want to save an architecture I have created
into xADL format. See story 5 for links.

Story 7
I want to have the graph auto-layout using one of
several algorithms such as spring-embedder,
dag, tree, layered, hierarchical. See
