The Document Object Model (DOM) gives developers a way to
address every element within an HTML file, allowing them to
use JavaScript to
- Add/delete nodes
- Modify node attributes
- Modify node contents

Making Decisions – Know your limits!
How much do you know?
How much are you willing to learn?
How much time do you have to learn?
Is your time best spent developing and maintaining technology?
What parts of this can you outsource?
Is your research project more about digital content or digital
methods? (you usually CAN’T do both!)
Homework
Find an example to discuss
Your own project
A project/site that you like
Questions
Main purpose of the web site?
Publication? Publicity? Community? Application?
Static vs dynamic?
Content management system?
How will it be funded?
Where does it reside?
Institutional? Private?
Is it more focused on presentation of content, or method (ie a tool)
