Free uml 2.0 activity diagram software for linux

MySQL Activity Report is a valuable database tuning aid.

The MySQL Activity Report package is a tool to help MySQL database administrators to collect several database parameters and variables. These collected values can be used for server monitoring or performance tuning purposes.

The most important component of the MySQL Activity Report is mysqlard. This daemon collects the data from a MySQL server and stores these values in a Round Robin Database.

The mysqlard package also contains example graphing, cron and php scripts. The cron scripts can be used to keep archives of the generated graphics and the php script shows the generated graphics and tries to give some tuning tips.

Netscape Friends Activity Sidebar is a Firefox extension that helps you keep tabs on what stories your Netscape friends are submitting, commenting, and voting on. A new toolbar button (shown in the extension preview image) features Chad, the older, more mature brother of AOLs little yellow chat mascot. When there is new activity by your friends (i.e., a new comment, story submission, or vote, depending on your settings), the button will be activated and Chad will send a friendly wave your way. Clicking on the activated button will open a list of your friends activity in the sidebar, allowing you to easily browse their stories and comments. Each time you view your friends activity, you will only be shown activity that is new since the last time you opened the sidebar.

Note: The sidebar limits activity to five items for each friend. If there are more than five items to view, a "View all of Chads activity" link will be shown at the bottom of the friends section. You can always view all of a friends activity by clicking on their name or avatar.

To make use of this extension, you must be logged into Netscape.com. If you do not have a Netscape.com account, sign up at http://www.netscape.com/signup Accounts are free, and it only takes a few minutes to create one. Once you have a Netscape.com account, you can submit stories and videos, vote for other peoples stories, rate comments, comment on stories you find interesting, as well as use this extension.

UML2PHP5 is a plugin designed to fit on the Dia diagram application. UML2PHP5 automatically generates the PHP code structure following the diagrams classes.
PHP5s and javas object model increasing similarity for example, there was an urgent need to update the tools for programmers.
UML2PHP5 is Open Source, under GPL. This means you can develop the source code to suit your need(s) and redistribute it as long as it remains under GPL terms.
Using UML2PHP5:
- Draw your UML diagram(s)
- Save it with .dia as file extension
- Export through the XSL filter (*.code)
- A popup opens :
- Select UML-CLASSES-EXTENDED in the top box
- Select PHP5 in the bottom box
- OK
The plugin generates as many .class.php files as necessary, in the same directory as the original .dia file.
Enhancements:
- A new tool was added: php2uml, which generates UML diagrams from PHP classes files.
- This tool uses the Reflection API.

uml2svg is an XSLT-based tool for converting XMI-compliant UML Diagrams into SVG.
We started the developing uml2svg with six main goals in mind:
- Standard conformance
- Good Documentation
- Modularity
- Extensibility
- Comprehensible SVG
- Multiple diagrams per XMI-file
SVG is a standard language for describing two-dimensional vector graphics in XML. As the open SVG standard gains in popularity and gradually replaces proprietary formats for vectorial graphics, the support provided by the Web browsers is getting better.
Plugins to display SVG exist for most browsers and it is most likely that the next generation of Web browser will provide built-in support for SVG. When that happens there will be no better way to distribute vector graphics on the web. Furthermore, not only web browsers can process SVG in a meaningful way; in fact that is just the tip of the iceberg. SVG can be easily read in, processed, and then transformed into many other formats, being well suited for both text and graphic tools as well as for web agents and screen readers.
UML diagrams are composed of lines, polygons, ellipses and text labels, so they are inherently vectorial. However, the SVG is not very well suited for direct use by UML tools. While some of them can in fact export UML diagrams directly to SVG, they do that by discarding all the information about structure, and converting everything into a shape. Moreover, some tools use the screen-capture function provided by their environment (such as java2d) and then they apply a filter to generate SVG out of the "screenshot".
What comes out of that is a pile of meaningless information, which by accident happens to draw a gorgeous diagram. How will a screen reader interpret such a file? How will a web crawler be able to index it? How will a web agent process it in a meaningful way? A program needs the semantic information that the humans can extract just by looking at a picture. For a machine, an obfuscated SVG file is not easier to process than a PNG file or any other image.
Although for humans it is better to be able to scale the image, for a program this is irrelevant. Programs need a way to "understand" the semantics of the UML models to be able to process and interchange them in a meaningfull way. This was the main idea behind the XML Metadata Interchange (XMI), an OMG specification for model interchange. And probably the best use that XMI has found so far is the exchange of UML models between different modeling tools. And while the XMI provides a standard way for tools to represent models as XML documents, it is still limited to the model elements only.
With the introduction of the UML 2.0 Diagram Interchange Specification as part of the upcoming UML 2.0 standard, it will become possible for tools to exchange the models together with the layout of the diagrams. We think that, once this specification appears, XMI will be used averywhere. Not only will the tools be able to exchange diagrams, but could even represent them internaly as DOM trees. Have you ever considered drawing your UML diagrams online, using only a web browser? This could be done even now by using a custom SVG syntax for the DOM tree, but a solution based on XMI could do even better and be a standard at the same time.
Therefore, we believe that with the advent of UML 2.0 and the increase in the use of SVG, the need for transformations between XMI and SVG will be great. Nevertheless when the uml2svg project was started, there was hardly any good open-source solution to convert XMI diagams into SVG.
The UML 2.0 Diagram Interchange Adopted Specification in its current incipient form references a set of XSL transformations. Although the standard draft covers them to a large extent, the link is actually broken (you can try for yourself). It has been broken for more than a year and most likely it will stay like that forever.
The personal webpage of Professor Mario Jeckle provides an online transformation service capable of dynamically generating SVG from XMI-compliant XML files. The XSL files accomplishing the transformations are also available on that website. These transformations are monolithic and not well documented (the only documentation is in the code, and it is generally written in German). With the tragic accident that took the life of Professor Jeckle, the transformations have no longer been maintained.
Finally, the STZ-IDA research center in Karlsruhe had to convert UML diagrams to SVG, as part of one of their projects. The XSLT stylesheet they created for this purpose was named xmi2svg and is available under the terms of the MIT license. At the time we started work on uml2svg the only type of diagrams supported was class diagrams.
Recently the package reached version 0.2 and it supports more diagram types, without major changes in the code (the opposite of what we were expecting). Andreas Junghans, the author of xmi2svg, provided us with a lot of insightful hints which helped us eliminate many glitches in uml2svg. It looks that the development of uml2svg and xmi2svg will continue in parallel, at least for a while. The good thing about this is that the two (quite different) implementations prove each others validity and the features tend to propagate freely from one side to the other. However, this comes with the prize of having to maintain two different code-trees and possibly confusing some users.
We did not like the two existing solutions because they were:
incomplete - just prototypes, not well suited for production environment
monolithic - hard to maintain and extend
not documented - hard to understand
At first sight, we thought we could find a way to improve one of the existing solutions and just add the features we needed. However, we slowly came to the conclusion that it would be better if we started anew. There are things one can fix in a project, but that does not include what we thought is was bad design. The fact that the two implementations presented above are open source helped us get quickly on the way with our own project.
Enhancements:
- Two annoying bugs were fixed.
- The site and documentation were updated.

UML::State is an object oriented module which draws simple state diagrams.

SYNOPSIS

use UML::State;

my $diagram = UML::State->new(
$node_array,
$start_list,
$accept_list,
$edges
);

# You may change these defaults (doing so may even work):
$UML::State::ROW_SPACING = 75; # all numbers are in pixels
$UML::State::LEFT_MARGIN = 20;
$UML::State::WIDTH = 800;
$UML::State::HEIGHT = 800;

print $diagram->draw();

ABSTRACT

Are you tired of pointing and clicking to make simple diagrams? Do your wrists hurt thinking about making the pretty UML your boss likes so well? Consider using UML::State and UML::Sequence to make your life easier.

UML::State together with drawstate.pl allows you to easily generate state diagrams. You enter them in something like a cross between ASCII art and school room algebra. They come out looking like something from a drawing program like Visio. See drawstate.pl in the distribution for details about the input format and the samples directory for some examples of input and output.

You will probably use this class by running drawstate.pl or drawstatexml.pl which are included in the distribution. But you can use this package directly to gain control over the appearance of your pictures.

The two methods you need are new and draw (see below). If you want, you may change the dimensions by setting the package global variables as shown in the SYNOPSIS. Obviously, no error checking is done, so be careful to use reasonable values (positive numbers are good). All numbers are in pixels (sorry by Beziers in SVG seem to require pixels). I have not tried changing the numbers, so I dont have any idea if doing so makes reasonable changes to the output.
