Ok I want to use MalGraphAlgorithm and MalGraphNode as superclasses for
Lattice and LatticeNode respectively, from Moose-Algos-Graph package. Now, I
think creating a third package would be a better option because that would
avoid the dependency:
FormalConceptAnalysis <-> Moose-Algos-Graph.
Should I create a package Moose-Algos-Graph-Lattice or Moose-Algos-Lattice?

Ok. That's a good place for lattice display. Is it normal that I
have Moose-MondrianPaintings-* but there is no Moose-MondrianPaintings
package in my image?

Hello Doru,
While porting the VW version of the lattice construction algos, the most
adequate representation for VW data structures was provided by Mondrian so I
used it.
Mistakes happen. But, it is important to learn from them :)
Now, I'll place them in Moose-Algos-Graph...
I am not sure what you mean. I did not mean that you should move the
Lattice classes in Moose-Algos-Graph. The Graphs should not depend on
FormalConceptAnalysis. I was just saying that the Lattice is merely a
support for creating a graph out of the FCA algorithm. In the VW version, it
was also a visual class, but it does not have to be. It should only contain
the logic of building the graph. Maybe for this purpose you can use the
Graph concepts. The display can be later build using a Mondrian script.
The display part can be moved to mondrian as an
extension of FCA. So, that
will break the dependency of FCA with Mondrian.
No. Like I mentioned before, the display should be moved to
Moose-MondrianPaintings. Mondrian is generic, and FCA is generic. They
should not know about each other.
The lattice construction algo can be moved into
Moose-Algos-Graph:
Moose-Algos-Graph classes can be used to construct lattices instead of
MONode. Now, lattice construction is not a simple graph construction and we
need knowledge of concepts to construct a lattice. So, lattice construction
would always depend on the concepts and then there is a dependency with the
package FormalConceptAnalysis. I do not see a way that the lattice
construction can work independent of FormalConceptAnalysis. Can you suggest
a possible workaround for this?
I did not say that it the construction should be independent. I simply said
that if needed you might benefit from the graph support. In any case, the
lattice will depend on FCA. So, either you place the Lattice class in the
FCA package, or we create another package that will depend on FCA and
possibly the graph one. The lattice does certainly not belong in the Graph
package.

Ok for the tests. I'll start creating them
now.
Please put them in the newly created package
(Moose-Tests-Algos-FormalConceptAnalysis).
Doru
I'll commit another version in the evening.
thanx
Usman
