My requirement is to create a diagram which can represent the object relationship which is stored in an xml.
For example
This needs to get translated as Class abc has a field which is xyz. This heirarchy can be multi level. and we need to represent
a) high level struturing of classes
b) contents of these classes.
I looked at some tools like umlet, violet, visio. but all of these require a lot of manual intervention. Is there a tool which can be configured to read from xml.
Try using Graphviz and the dot language.
http://www.graphviz.org/
You'll need to write a translation layer, but that shouldn't be too hard in the language of your choice.
UModel might be a good pick for you on this one... http://www.altova.com/umodel/xml-schemas-in-uml.html

I need to draw a more elaborate Mindmap to present my test strategy to my client. I have no experience of creating mind map with any tool.
Can someone suggest any good mindmap making tool?
For "pure" mind mapping I would suggest Freeplane (free and open source). I know people using Freeplane for professional test case generation. Very helpful in this respect are
extensive scripting support that can be used to support testcase entry and for customized exports
multiple fields per node that can be used for different purposes: attributes (tabular data), notes, detail
If your primary focus is the generation of presentations then you should probably use a different tool.
For more elaborate mindmap I would suggest XMind.
With XMind you can even create testcases inside your mindmap using its matrix features. There are lots more features like:
Timeline
Gantt view
Filters
Drilldown
Try https://github.com/mindolph/Mindolph , this desktop application provides features that you can create and manage mind map easily.
You may try online service MindMup or desktop ConceptDraw MINDMAP. Though the first one is not that professional and intuitive as ConceptDraw tool, it is free. The second product has a 21-day trial period, brainstorm mode, multiple hyperlinks, export to MS PowerPoint or Web pages and so on.
I need to fix my Alloy graph, for example I have this output:
I can't move "node2" rectangle over the row of "node0" and "node1", and I can't move "node1" under "node2" whitout also move "node0". Is there any solution? Thank you.
PS: I am using Alloy Analyzer 4.2 under Windows.
PPS: This is only an example, i get a big graph with 5 or 6 rows of 20-25 rectangles, and if I can't fix it manually, it's only a mess.
To answer the direct question: I for one have never found a way to make the visualizer change its mind about which nodes should be on the same horizontal level. (That doesn't quite mean it's not possible, but it does mean that if it's possible it's not immediately obvious how to do it. But I guess you knew that already.)
If your goal is to make the auto-generated diagrams easier to read, the simplest approach is to experiment with adjustments to the visualizer theme. The "Magic Layout" button can be helpful; manual adjustments to hide some nodes or display some relations as labels rather than arcs can help with diagrams which are otherwise too cluttered.
If your goal is to make a 'good' version of a diagram for inclusion on a slide for a talk or a figure for a paper, you may want to export to Dot and import into a graph-drawing tool that gives you the kind of manual control you want (or edit the .dot file yourself, if you are familiar with graphviz and can make it do what you want), or export to XML and generate the graph description language of your choice from the XML.
I hope this helps.
The Lightning tool is an Ecplise plugin relying on Alloy4.2 to formally define Domain Specific Languages and might be a solution to your problem.
It's still under development, but if you are only interested in being able to freely reorganize each atom and label of generated instances, there shouldn't be any problems, as it uses Ecplise draw2D to render those latter.
If now you're really interested in providing an intuitive visualization to your generated instance (by intuitive I mean a visualization that is closer to its domain rather than the structure of your model), then you can define your own language (with your model as abstract syntax ) and define a concrete syntax for it.
The update site to be used for the installation of the tool is : http://lightning.gforge.uni.lu/update-site
Don't hesitate to contact me if you plan to give it a shot and get any issues.
(I'm eager of constructive feedbacks ;-) )
The steps to follow to generate a graphical instance in which any components can be moved are :
Install Lightning
Create a new Lightning Project
Create a new Language in this project
Put your model in the ASM folder
generate instances of the language by "running the project"
I'm looking for an online tools where me and my team could collaborate on creating graphs.
The purpose is to bind related words, and generate the adjacency list. For example,
Foo----Bar----Brool
|_____Lol
will generate the following list :
Foo,[Bar]
Bar,[Foo,Brool,Lol]
Brool,[Bar]
Lol,[Bar]
The idea is to allow people to collaborate simply using graph visualization, without diving through the adjacency list directly.
There is one service wchich I believe is going to be designed to allow people to collaborate on creating a graph. It is Graph Commons. Site slogan says:
Collaborative 'network mapping' platform and knowledge base of relationships
Unfortunately at the moment you can only sign up for beta invitation on the website. And from the website it is not clear what the creation/editing mechanism would be.
You could use yfiles library to build a graph editor online, but I've never used it and I don't know if you can manage multimple sessions (hence allowing direct collaboration). But, for instance, if you use graphity, which is an implementation of yfiles flex library, and save a file on dropbox, then each collaborator has access to that file, and you can set up a rudimentary collaboration graph tool. Maybe.
It would be great to have tools like LucidChart or Draw.io, but they don't allow to export a graph file (e.g. graphML from which you can then have an edgelist with some other programs like Gephi). Those tools only allow you to export images and vectors. Draw.io exports xml, but not graphML.
I believe Linkurious let you edit your graph. Again, I've never used it, I don't know if you can manage multiple sessions > collaboration. But I would check it out. Edit: Linkurious enterprise edition (see pricing) is desegned to handle multiple user sessions.
What about building something with vis.js? The library has the ability to «listen for changes in the data» using a DataSet component. Have a look at this example.
I'm sorry if I don't have any real answer, but since your question is very interesting in these days, and the right tools would come out sooner or later (if it doesn't exists), I wanted to share these thoughts. I hope they can help. Please post when you find a solution!
I'm building an application that parses text files that contain information about specific nodes with incoming ports and outgoing ports that are interconnected. Doing some research there are some libraries but none of them support the exact characteristics needed.
this is what I'm trying to build and any language will do: Python, Perl, .net, etc.
One of the libraries I have found is GoDiagaram Node Classes
http://www.nwoods.com/components/dotnet/features-nodes.htm
The idea is to have boxes like so, interconnected and I should be able to click on one of them and link it to a new sub-diagram with more boxes contained in the one clicked.
Is there a counter part of these kind of charts that is opensource? and do these diagrams have a specific kind of name?
I don't know any specific details, since I never looked into this too closely, but here are some potential directions:
The data structure used for representing something like this is usually a graph (probably a directed graph). You could also try searching for graphical (or visual) programming languages. I seem to remember Pure Data as one that was relevant, but I never looked at it in detail.
Blender and VirtualDub both have a mode that's similar to this (the node editor and audio filters, respectively) and I believe both are open source, although I think neither has the option of having the nodes contain other nodes internally.
You could just use LabVIEW, which gives you the ability to create and edit LV code programmatically (search for "VI scripting"), but the code for that might not be very pretty and it's certainly not open source.
I want to use RDF / triples in my Symfony2 project in order to organize things (in my case it is Tags).
I would see something like this :
ENTITY TAG <-------------- TAG_TAG --------------> ASSOCIATION_TYPE
^ |
|---------------------/
Fields :
TAG
ID
Tag (text)
Description (text/html)
TAG_TAG
ID
*TAG1
*TAG2
*ASSOCIATION_TYPE
ASSOCIATION_PARAM
Like this, I would be able :
To store triple associations
To set different association types. For example, PHP is a Programming_language ; stackoverflow.com is a website ; but the Earth turns around the Sun.
To set parameters (which permits to give more information inside associations)
We could consider setting a many-to-many relation between TAG_TAG and ASSOCIATION_TYPE. By doing this we could set several parameters.
So I have several questions :
Do you think it's a good way to store triples efficiently ?
Is there any RDF layer to extract existing RDF/triples databases and populate my own ?
Should I consider using some kind of tripleStore like Sesame and use it with Symfony ?
To answer your questions:
1) I'm not entirely sure what you're asking. If you're asking if that's a reasonable way to model your data, it's probably ok. But your diagram is not clear and you're a bit light on details. Best thing to do is just do something that works to start with. You can improve the modeling later without much of a hassle.
If you're asking about storage of triples, don't. See my response to #3.
2) There are many RDF libraries available, you have Jena & Sesame in Java, dotNetRdf for the .Net world, RDFLib in python, redland for C, etc.
3) Yes. Don't attempt to re-invent the wheel and build your own triple store. It's not an easy project and you won't do better than even the worst existing triple store on any reasonable time scale.
As Michael said - please don't build your own triple store! There are several solutions available in PHP:
ARC2 provides a triple store based on MySQL
The librdf extension provides a PHP wrapper for the standrad RDF C library
The Erfurt Library is an abstraction library for connecting with the open source Virtuoso Server triple store, but also has its own triple store based on Zend DB taht can be used with MySQL.
