Hi, for long term serialization I would also look for an other mechanism than implementing Serializable. I would prefere an ASCII/JSON/XML kind of externalizable format. This would have the advantage of not being limited Java, but open for processing with other languages. I did not see use ca

Hi all, as I am also interested in short term serialization just for moving objects between a distributed virtual machines and not in long term serialization, I would support the discussion up to now. To express our intentions we could make an interface, say public interface Transportable ex

[Math] Proposal for a set of interoperable interfaces for mathematical structures

2012-01-21 Thread Heinz Kredel
Hi, I develop a computer algebra system in Java (JAS) at http://krum.rz.uni-mannheim.de/jas/ The system has only limited capabilities for linear algebra and its main focus is on general commutative and non commutative algebras. So I would eventually like to use linear algebra algorithms fr
