This is a presentation I gave on using Fluidinfo with the Cactus Computational Toolkit. I also describe FluidCV, a social resumé project I'm working on.

10. About Tag
Unique tag fluiddb/about
Gives the object some basic meaning

11. Namespaces
Group tags
gridaphobe/employer
gridaphobe/publication/journal
gridaphobe/publication/title
Wednesday, February 23, 2011

12. Permissions
Secure tags and namespaces
Create
Not the exact list,
Read
but these are all
Update possible!!
Delete
Wednesday, February 23, 2011

13. Queries
Natural Language
“has gridaphobe/employer”
“gridaphobe/rating > 4 and has gridrebel/
read”
Wednesday, February 23, 2011

14. So why is this
better than a
traditional
database?
Wednesday, February 23, 2011

15. We have a Ton of data
Simulation results
Machine configurations
Thorn metadata
Authors, URL, Language, License, etc.
Wednesday, February 23, 2011

16. Metadata
This is where Fluidinfo really shines!
gridaphobe/cctk/[authors|url|language|
scm|purpose|...]
Now I can get a list of all the thorns I have
tagged with “has gridaphobe/cctk/url”!!
Wednesday, February 23, 2011

17. Einstein Toolkit
ExternalLibraries/Python
Personal thorn (defunct actually)
How do we know that it’s not part of ET?
einsteintoolkit/includes ET
approved!
“has gridaphobe/cctk/url and has
einsteintoolkit/includes”
Wednesday, February 23, 2011

18. But Eric isn’t an
author of any ET
thorns?!
Wednesday, February 23, 2011

19. Good Point!
[knarf|eschnett|hinder|...]/cctk/[url|scm|...]
Thorn authors keep their metadata updated
Also add simple “cactuscode.org/thorn-
author” tag to user object
Now I know who is using the tags

21. Voila!

22. Voila!

23. FluidCV
Shameless self-promotion!
Wednesday, February 23, 2011

24. What else can we
mark up?
Personal info
Jobs
Education
Publications!
Wednesday, February 23, 2011

25. Personal Info
gridaphobe/given-name
gridaphobe/cell-phone
gridaphobe/summary
etc.
Wednesday, February 23, 2011

26. Jobs
gridaphobe/employer
gridphobe/company
gridahobe/title
gridaphobe/start-date
Wednesday, February 23, 2011

27. Education
gridaphobe/school
gridaphobe/degree
gridaphobe/major
gridaphobe/honors??
Of course!
Wednesday, February 23, 2011

28. Publications
gridaphobe/publication
gridaphobe/publication/authors
gridaphobe/publication/journal
gridaphobe/publication/doi?
unnecessary if we make it the about tag
fluiddb/about=“doi:

36. I’m excited!
But how do I use Fluidinfo in my code?
Wednesday, February 23, 2011

37. Libraries
Python, Perl, Ruby, PHP, Java
fluidinfo.com/developers/libs
Even C++!!!!
Work-in-progress
