Quick Recap

• The Data Model
  • Codecs
  • Traversal
  • Philosophically: Legibility and Generic Transforms

• More cool stuff
  • Data Structures (sharding, encryption?, ADLs)
  • Schemas (design languages!)
  • Programmatic Transforms...?

goals

(much briefer)

but first

building the next git...

should take hours, not days.

overall,

Quick Recap: Wtf is a codec?

• A codec is a function that goes from
     {serial bytes} -> {IPLD Data Model}
   
• Or the other way around.
  
  
  
  
  
  
  .... okay so wtf is a data model

Quick Recap: "legibility" and
the Data Model

• map, list, int, string, bool, bytes, link
• okay, fine, float, but i don't want to talk about it
• it's enough to path over it

Quick Recap: Traversal

So you can probably see how this pretty much falls out of the "legibility" thing.

{"foo":{"bar":{"baz":42}}}

traversal.Get(that, "foo/bar/baz")

-> 42

"more cool stuff"

• Selectors (graph walks, declaratively)
• Data Structures (sharding, encryption?, ADLs)
• Schemas (design languages!)
• Programmatic Transforms...?

(We're gonna have to go over these sofast)

Cool stuff: Selectors

if you can step, you can walk

->

Cool stuff: ADLs

• what if something implemented "Node"...
• but all the functions for a "map"...
• actually looked up more blocks,
  used a sharding function to nav a tree,
  and did cool stuff?
  
  Yeah hi that's ADLs.  Plugins where
  the result acts like Data Model.
  
  (Select over it...  you know want to...)

Cool stuff: Schemas

• i'm gonna straight up return EAGAIN
  on this for time constraint reasons
  
  
• check out the specs and docs site,
  or ask me for another session on this
  
  
• they're selfhosting and selfdescribing
  and frankly kinda neet
  
  
• structural typing on top of the DM

Cool stuff: Programmatic Transforms

• Shallow end: "IPLD Patch"?
  (not today, maybe soon)
   
• Deep end: whole interpreter
  and environment?

Sure why not

Hold on for more news throughout the week,
I've heard...

IPLD is about a lot more than blockchains.
