Free mindmap software
Got this link from Semantic Blogger demostrator, FreeMind is free mind mapping software, written in java.
Going from the screen shots alone, it looks as good if not better than my pocketmind map software on my ipaq. It is also ment to support export to xml? Which schema it uses i dont know, but I'm sure I can knock out a what ever to topic map xsl, if someone hasnt already done so.
HP’s Category Chooser
Another semblogging component, Category Chooser.
Fantastic idea, could be great for those times when your not sure what catergory to put the post in. Sometimes you can spend a good few minutes changing your mind back and forth between two catergories. Would be great to have some systematic advice.
Os david demo
David marks has finally sorted out a demo of his beatiful but clever project os david.
Here's the very large quick movie for the project. I expect david will put the project online at some point in the future, if he can find a host which will give him lots of bandwidth and xmldatabse storage.
Semantic blogging, navigation and tree
Semantic navigation
Tree view navigation, with Developer weblog
Almost worked on my new ipaq too!
Seriously these guys at HP, are truly coming up with some very useful applications using simple technologies.
Oh also saw this on my travels,
New updates from the author of Blucene. I have not installed or looked at the docs yet, but it allows you to post and delete using a form i believe?
Describing pictures using rdf
Oh my goodness, I dont believe what I am reading. It started off by reading Steve Cayzer's blog. And before I knew it I had 4 tab open looking at different sections in this area.
I truely can not point out how amazing this really is. I've always thought of wrapping images up in xml, not embedding it in. Actually tell a lie, I didnt think it was possible? think of things as if your in the matrix. its just code, so why not?
Anyway heres the w3c rdf photo site outlining the spec. Seriously it brought tears to my eyes.
The goals of the project are partially personal, partially to promote W3C technology. The personal reasons are that we, the authors, have large numbers of photos but always have difficulty finding the exact ones that we want to show to somebody. Digitizing them and describing them in RDF should make it quicker to find the ones we are looking for at any moment.
So what does this all mean? Well in the case of david mark's project os david. (see david if you used xhtml instead of flash, i could link directly to the project, and if xpointer was working fine I could quote directly from your own text).
David has wrapped up his images and videos with xml and wrote a very beautiful interface to navigate around the data. Now if we applied this, we could query the images themselves rather than xml documents.
However one of davids problems was calculation speed, so he used a xml database. Which makes me wonder if there are any databases which support images but wont destory the rdf? Now that would be a good project for someone.
Also on the same tagent, what would photoshop or something like that do to this rich rdf data? I know it kills camera data.
Rdfpic, a real working application written in java, hoping to experiment with it over the weekend
The other side, jpegrdf, getting the data out.
Now if someone wrote a serializer for cocoon which did this, I would be xstatic. And why not? its written in java, sure some one will work it out soon.
There is also talk of intergration into Adobe's Extensible metadata platform which I havent looked at for over 3 years now. Will have to spend more time looking into this later.
All this also bring me back to thinking about Annotea which is a advanced annotation/note tool.br/>
Anyway yes I would like to experiment with this too, specially now they have a client built into Mozilla – Annozilla
Have a look at how powerful this could be Screenshot from current version
Topic maps
Even though I know there not compareable, opml and topic maps. I will use them in simular situations. Or at least write down notes using a outline tool which supports opml then convert them into topic maps.
I'm finding more than ever the need to keep a track of the actual relations between different things. Not just the things themselves.
Good starting points

Company selling topic map software and a free topic map viewer, they also have some ok papers on topic maps. Including topic maps, rdf and other semantic languages
