Unified Modeling Language upgrade proceeds

The UML (Unified Modeling Language) standard would be fitted with a modeling library for implementing tools, under a plan to be submitted to the Object Management Group on Wednesday.

UML is a specification for constructing, documenting, and visualizing software systems.

U2 Partners, a consortium of vendors that has been working on the upcoming version 2.0 of UML, plans to submit a technology called UML Infrastructure Library, which is designed to make Model Driven Architecture Tools more efficient to implement and integrate with each other, according to a spokesperson for U2 Partners. The proposal is to be submitted at the OMG's meeting in Orlando, Fla.

UML 2.0 is being developed in phases to cover areas such as language infrastructure, diagramming, and low-level language details, said Matt Graney, product marketing manager for San Jose, Calif.-based tools vendor TeleLogic AB, which is participating in U2 Partners.

Version 2.0 addresses deficiencies in the initial iteration of UML, which has been around since 1997, Graney said. UML 2.0 is intended to make it easier to develop complex software systems, he said.

"The size of the software systems that are being built are just enormous today and as a result, engineers and software [designers] need a way to manage complexity," Graney said.

UML enables developers to have a common understanding of problems to be solved as well as implementations and solutions, said Graney.

Version 2.0 is expected to be completed this year, he said.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
