Definining and using typed graphs

Dear all,


We are starting a number of projects which all use graphs as
underlying data structure. We need a software package to manage these
for us. We are looking for something with the following properties:


- typed nodes


- typed, labeled, directed, binary edges


- node attributes containing ordinary data values


- node typing should allow for sub-typing


- possibility to define and use a graph typing within a single session


- possibility to save a graph (and its typing) to file, and load it
    from file


- implemented in C or C++, callable from C++


We are thus looking for the structuring and navigation primitives of
an object-oriented database, but which is less concerned with file
stores and processing of huge amounts of data.


Would you know of a public domain (or not too expensive) package which
runs under Unix and offers (some of) the above properties?


Kind regards,
Jan Rekers
