"I get to write as I learn my way... for those reading, this is an invitation to join me and us."

Deja's (@dejachy) journey with @Xalgorithms began here. Check out her first #blog post to learn about her role and other contributors!

Growing up in Canada’s Flag of Canada port city of Halifax, #trade has always been a part of Craig's (@craigaatkinson) life.

Now, with @Xalgo4Trade, he’s on a mission to advance #rules and the #Internet for #tradefacilitation and #digitaltrade.

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:

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.

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.
