What?

FluidDB is a platform for the web of things, each
represented by an openly writable "social" object.
Why?




                  http://www.flickr.com/photos/psd/4123236978/



We want to make it easy to share, annotate, augment
and re-use information.
How?

Objects are simply tagged with information
Key Concepts

           • Objects - represent things*
           • Tags - define objects’ attributes
           • Namespaces - organise tags
           • Permissions - control access

* NOT instantiations of classes as in OO, but simply “objects” in the common-sense use of the term.
Data Structure


entity / attribute / value
Data Structure


object / tag / value
   (in FluidDB parlance)
Namespaces and tags are
   pre-defined by users
             ntoll/rating
             terrycojones/books/review
             amazon.com/book/title
             amazon.com/book/author
             amazon.com/book/isbn
             esteve/books/cover
             timoreilly/has_read
(Every namespace and tag has a description and is itself
 represented by an object so meta-tagging is allowed)
A basic object:


    about =        An                        id =
                           “e127475b-eb93-48e1-a24f-dde6825b9ed8”
  “book:Dune”     object




(The about tag is a convention to help indicate
what the object represents. It is optional but
must be unique)

Permissions

• Apply to namespaces, tags and tag-values not objects
• Scoped by actions (e.g. “see”, “create”, “read”)
• Either “open” or “closed” with a list of exceptions
FluidDB’s Query Language
 •   Equality & Inequality: To find objects based on the numeric values or
     exact textual values, e.g., tim/rating > 5, or geo/name = "Llandefalle".

 •   Textual: To find objects based on text matching their tag values, for
     example, sally/opinion matches “fantastic”.

 •   Presence: Use has to request objects that have a given tag. For example,
     has sally/opinion.


 •   Set contents: The contains operator can be used to select objects with a
     matching value in a set of strings. The query mary/product-reviews/keywords
     contains "kids" would match the object with a tag called /mary/product-
     reviews/keywords and value ["cool", "kids", "adventure" ].

 •   Exclusion: Exclude objects with the except keyword. For example has
     nytimes.com/appeared except has james/seen. The except operator
     performs a set difference.

 •   Logic: Query components can be combined with and and or. For example,
     has sara/rating and tim/rating > 5.


 •   Grouping: Parentheses can be used to group query components. For
     example, has sara/rating and (tim/rating > 5 or mike/rating > 7).
er... that’s it

FluidDB for Dummies

  • 2. What? / http://www.flickr.com/photos/psd/1428129861 FluidDB is a platform for the web of things, each represented by an openly writable "social" object.
  • 3. Why? http://www.flickr.com/photos/psd/4123236978/ We want to make it easy to share, annotate, augment and re-use information.
  • 4. How? http://ntoll.org/images/93.jpg Objects are simply tagged with information
  • 5. Key Concepts • Objects - represent things* • Tags - define objects’ attributes • Namespaces - organise tags • Permissions - control access * NOT instantiations of classes as in OO, but simply “objects” in the common-sense use of the term.
  • 6. Data Structure entity / attribute / value
  • 7. Data Structure object / tag / value (in FluidDB parlance)
  • 8. Namespaces and tags are pre-defined by users ntoll/rating terrycojones/books/review amazon.com/book/title amazon.com/book/author amazon.com/book/isbn esteve/books/cover timoreilly/has_read (Every namespace and tag has a description and is itself represented by an object so meta-tagging is allowed)
  • 9. A basic object: about = An id = “e127475b-eb93-48e1-a24f-dde6825b9ed8” “book:Dune” object (The about tag is a convention to help indicate what the object represents. It is optional but must be unique)
  • 10. r= ve s/ co k oo ntoll/ b ve/ te es rating am azo n.c “87 om/b -41 ook =5 8-7 517 s/isbn -6” = about = An id = “e127475b-eb93-48e1-a24f-dde6825b9ed8” “book:Dune” object = am a iew zo timoreill v n.c /re s” = s om r ok rm er tho /bo wo “D /bo nes and un ok erb s/au ojo ve s e” s/t t” y/has_re ryc I lo it k H ok le ter “ = ran /bo “F om ad n.c azo am

  • 12. A simple and elegant RESTful API https://fluiddb.fluidinfo.com/objects/OBJECT_ID/NAMESPACE(s)/TAG HTTP ‘GET’ returns the value, HTTP ‘PUT’ adds/updates it etc... Full API: http://api.fluidinfo.com/fluidDB/api/*/*/*

  • 14. r= Traditional: oo k s/ co ve ntoll/ b ve/ te es rating am azo n.c “87 om/b -41 ook =5 8-7 517 s/isbn -6” = about = id = “e127475b-eb93-48e1-a24f-dde6825b9ed8” “book:Dune” = am a iew zo timoreill v n.c /re s” = s om r ok rm er tho /bo wo “D /bo nes and un ok erb s/au ojo ve s e” s/t t” y/has_re ryc I lo it k H ok le ter “ = ran /bo “F om ad n.c azo am

  • 16. Permissions • Apply to namespaces, tags and tag-values not objects • Scoped by actions (e.g. “see”, “create”, “read”) • Either “open” or “closed” with a list of exceptions
  • 17. FluidDB’s Query Language • Equality & Inequality: To find objects based on the numeric values or exact textual values, e.g., tim/rating > 5, or geo/name = "Llandefalle". • Textual: To find objects based on text matching their tag values, for example, sally/opinion matches “fantastic”. • Presence: Use has to request objects that have a given tag. For example, has sally/opinion. • Set contents: The contains operator can be used to select objects with a matching value in a set of strings. The query mary/product-reviews/keywords contains "kids" would match the object with a tag called /mary/product- reviews/keywords and value ["cool", "kids", "adventure" ]. • Exclusion: Exclude objects with the except keyword. For example has nytimes.com/appeared except has james/seen. The except operator performs a set difference. • Logic: Query components can be combined with and and or. For example, has sara/rating and tim/rating > 5. • Grouping: Parentheses can be used to group query components. For example, has sara/rating and (tim/rating > 5 or mike/rating > 7).
  • 18. er... that’s it (QL fits on one slide and enhancements are coming soon)
