Thanks for the reply and the info.
I'm taking a look into /trunk/servlet to see the source code, just for curiosity. Indeed web technology (in particular its frameworks) has changed since then. The "web port" I imagine would most probably employ some frameworks (definitely one for persistency, probably Hibernate).
I'm glad to hear you would be happy to see efforts towards this...

Hello Alexandre,
thanks for the positive feedback on the project and our paper.
The idea of having a web-based system has been around for a long time, in fact many years ago we got one of our students to implement a prototype rendering the diagrams as SVGs on a web page:

I'm not sure that code is something I'd reuse...

Hi ToscanaJ community
First, congrats on great work done at ToscanaJ!
I have read about (and tried out a bit) ToscanaJ for implementing Conceptual Information Systems, and I'm very interested in it (im currently an MSc student).
I think I have understood quite well the components and workflow of a Conceptual Information System (I have read the paper by Peter Becker, Joachim H. Correia...

The more you describe the more I believe that you would be much better off using Siena with the OAL or CXT format.
Storing the formal context as table with boolean values in a database is neither efficient nor well-supported by Elba -- it just never was a use case we considered important since normal database schemas tend to look a bit different.
There is a way to get what you want...

something like this...
obj1 as label and its clause -...

I suspect that you created the SQL file as a MySQL dump, which will contain some processing instructions that are specific for MySQL. Look at the file in a text editor and make sure it contains only SQL instructions, from what you describe I would expect a single CREATE TABLE statement and one INSERT INTO per row.
Note that you could also run into a few more issues with MySQL's SQL not...

Hi again..
As u mentioned i created my table into mysql DB and now i was trying to connect this db with ELBA so that i can view the concept lattice generated. However my table is a bit different than as shown in Elba manual... my table has objects as rows and attributes as columns and the data is only 1s and 0s depending on whether the object has that attribute.. i m not sure whether elba...
