Thanks so much for your comments about my presentation. The feedback I've received from you and our other classmates will make my project a lot more rigourous.
To answer your procedural question, I will do an online DACUM (the junior/entry-level psychometrician) with a group of 6 experts. I will note and report on what worked and what didn't. As you know, DACUM is a pretty reliable process. If the result of the online DACUM is not comparable (number of competencies and tasks) to a F2F DACUM, I suspect the causes will be with me, as the facilitator, or the online process/tools, or a combination of both. I will make changes to the my facilitatin technique and/or the online process/tools in a second, related DACUM (senior psychometrician) with the same group of experts.
This is not ideal. But I believe it will provide enough information as an exploratory study to "plant a stake in the ground" from which further research may be done.

Week 8 - Thoughts
This is some heavy reading, which incolves some very technical details. Interesting to think aboput developing a protocol or standard for social system. the very nature of social system is to find people and connect to them and in some cases, meeting with people that we barely knew. However, email is a bit different where usually they are send to known people. One challenging task would be to provide accurate details in social system while not being too restricted. For example, social sites does not have strict rules on the type of picture a person can upload to their profile. They can upload the picture of their dog if they want to. However, if emails would have pictures of the sender, they would upload their own picture. Ho can a system be developed to keep it casual but have corect details? Maybe that is for future tudy.

Week 8 - Interoperability and Standards
Problems trying to solve: Have a full-fledged client side application that uses technologies such as HTML and then packaged for distribution.
Obstacles to adaptation: the application is packages as zip file which can be difficult for some operating systems such as older Macs to unzip and utilize files. However, additional applications such as 7zip or WinRAR can be used to extract and edit files.
Weaknesses: Zip file must be created in a specific way and older Mac software would have issues zip files and default program.
Strengths: Open source software, developers can provide constant feedback and help to make better versions.
Problems trying to solve: provide stateful, real-time server-to-browser communication protocol without using plugins such as Flash or Java applets. Alternative for XML.
Obstacles to adaptation: Because of open source and security issues, this can be misused. However, the adaptability is good due to it being open source.
Strengths: open source and language independent. It has low-overhead compared to XML.
Problems trying to solve: SOAP exchanges data across various browsers and operating system as it uses XML.
Obstacles to adaptation: Because of security, the messages can be larger than using other protocols. For example, financial messaging using SOAP can lead up to 4 times larger message compared to older protocols. However, this would provide higher security.
Weaknesses: HTTP without using ESB or Web Services Addressing results in only one client using the service. Slow parsing speed of XML and lack of standardization leads to use of other protocols.
Advantages: SOAP is neutral but most common implementation is with HTTP. SOAP with HTTP post/response does not require modification of firewall for communication. SOAP is available to XML.
Creating your own standards
A standard for a distributed system should follow a similar protocol like HTTP. Such a protocol would ease the transfer of data across various systems just like an email can be directed to various providers. The standard should be open source and have security features built in. Social systems must share from whom a message is coming along with a geographical location such as city for easier identification and tags such as common interest. These tags can be used to find people with similar interests or near geographical location. Dead links can be taken care of an automated script trying to find links along with a service where users can provide feedback.

Week 7 - Second field trip
Interesting field trip, had great time in virtual world and explored a bit. I have not been to Athabasca University main campus, so I do not know how it is, but in virtual world I was able to see the building.
Also, it is great to meet fellow students and have fun with them. I found it neat to do some activities together in virtual workplace, even though those are a nit challenging.
Unfortunately, we were unable to customize our avatars. It would be more engaging if we were able to customize those avatars and potray them closely to how we are.
One part of excercise felt different, we know we are still in same virtual place but when we turn our backs together it felt like we are not in the same environment. One thing that gave the "isolation" feeling is when we started flying and everyone went in their own direction.
Interacting with things is cool and so does sitting together and chatting, it wuld be easy to replace the building and time of day with beach and that would relax us even more.
