"The general problem to solve in my case, as in many scenarios, had to do with how we communicate which way is forward when orienting decisions involving many people."

Suppose we consider expressions of obligation, permission or encouragement to constitute a distinct class of data:

IS + RULE --> OUGHT

1/ Have you seen the blog/demo videos for the #EarthReserveAssurance (#ERA) use case to align #economic and #environmental incentives?

The #AgentBasedModel (#ABM) was created through various members at the Center for Connected Learning at @NorthwesternU.

2/ Until now, the world lacked a scalable and efficient way to communicate obligation, permission or encouragement from 'rule-makers' (including you) to 'rule-takers' (including you).

---

3/ We noticed that data expressing MUST, MAY and SHOULD, plus their various negatives and synonyms, comprise a class of #data with intrinsic directionality. 

These terms even have their own #standards:

https://tools.ietf.org/html/bcp14 

https://iso.org/sites/directives/current/part2/index.xhtml#_idTextAnchor078

---

4/ So, we optimized a way for #DataWithDirection to be discovered and transmitted over the #Internet in a form directly usable by non-specialized humans and machines, for any purpose, in any language. #DWDS

---

5/ The #DWDS #RuleSchema is a concise #datamodel at the core of the #DataWithDirection Specification.

DWDS #RuleMaker, #RuleTaker and #RuleReserve are the three functional parts of a data-processing pipeline for sifting out IS + RULE --> OUGHT relations.

https://doi.org/10.1109/TVCG.2016.2603178

---

6/ @Xalgorithms Alliance participants are creating three reference implementations (developer / operator / modeller) on distinct platforms.

---

7/ #DWDS enables a wide diversity of potential use cases. Early collaborations involve #trade (@Xalgo4Trade), monetary system integrity (#ERA), and dynamic indexed pricing, etc.

---

8/ All use cases and functional components together constitute an emergent #InternetofRules -- a name proposed by @jrpotvin in 2016.
