Redvant

Précis

Redvant , or 'dcms<' (dcms-bra), is an collective term for software including react and servant within a DCP context and packaged as a reusable resource demonstrated in various applications such as the tl:dr and by the KEE.

"red" could be

react, redis, light in the ~700 nm range, a proper name as in red5, the parfume, riding hood, Malcom X, Simply, etc..

and "vant" is just from haskell-servant.

Use of Apache ISIS or other fat DDD pkg is intended later in the development our overall DDD product line engineering (i.e. a 'redvantis'). Some enterprise users may prefer the java basing of ISIS or an ERP core and these future developments are anticipated after the foundational elements are established.

Specification

At this time, this § is the sole exposition besides the code of any forks of constituent 3rd party packages in my public github or my original ones in my private git repo. It is accounting oriented and doesn't address the full actual scope of use as implied by the next ¶.

The model use cases are the AC SPA and the Ft doorbell, as well as GT2 2.1 and later and the tl:dr product line, in sofar as their front and middle are concerned.

Scope

Redvant carries our use of react and related node based stuff on the core purpose of transacting and accounting in domain space systems and apps. As such it is deeply integrated DCMS, DCP, etc. but these interfaces shall not be required in the product and its operation without them is a design requirement.

Accounting

Principles

Abstraction and Unity

Ledgers are abstract entities realized differently in different packages but from the perspective of a single accounting ontology.

Unless qualified, 'ledger' means double entry accounting ledger, a fundamental concept conserved across all ledger implementations, the basis of their unification.

Packages

hledger

The user reference ledger, how individuals and groups view their ledger.

ledger

The plaintext reference ledger, how the system views all ledgers.

SQL-Ledger

The enterprise reference ledger, how firms view their ledger.

Transacting

django-oscar

Provides front end and tx'ing code. We introduce the notion of an ephemeral tx ledger, oriented to a single, possibly complex tx which is connected to the others. Like 'ledger' transaction, 'tx' is defined to be an abstract change to a ledger. The process of application of an real such change to persistent ledgers is called settlement.

Commonalities

The same boat small form factor common reusable base with ...

1. DS SSO, messaging, and DCMS API setup for product families.
2. Videotelephony, defaults to Jitsi.

Deliverables

• tl;dr product line engineering cases for GT2, TASKPM, and YAS3FS.
• stable production level Ft and AC SPAs
