==== Description: ====
ikil database will be written in GNU Guile. It has the best of the popular
databases:

- It will be schema free like document databases (mongodb, rethinkdb,
couchdb). the main interest of this feature, is the ability to alter the
schema - on the fly - without running a particular command or moving the
database offline.

- Unlike document databases, it has cross documents (global) transactions. 

- Documents are "json-like", fields value can be numbers, strings or list of
strings or numbers or lists.

- It will be possible to link documents together like in relational databases,
except links are not constrainted by a schema. 

- Unlike document databases, links are part of the transaction semantic, so no
broken database.

- Actually, ikil database is the result of a reflexion regarding graph
databases. The differences with graphdbs is that there is no "edge"
*documents*. To the contrary to the dominant marketing, having to deal with
two kind of documents is a burden, and refying edges documents too. Instead
they are lean directed links tuples (document-a, field, document-b).

- There is no supernode issue in ikil database [0]

- Unlike OO databases links can be queried both ways.

- It will be written in GNU Guile using Guile Wiredtiger (submitted
previously).

- Indexing for integer and string fields will be possible.

- It has strong ACID capabilities thanks to wiredtiger.

Last but not least, querying is done in GNU Guile.


==== Other Software Required: ====
GNU Guile GPLv3
Guile WiredTiger - https://github.com/a-guile-mind/guile-wiredtiger (submitted
to nongnu.org too)
wiredtiger - gplv2 or gplv3 -
https://github.com/wiredtiger/wiredtiger/blob/master/LICENSE


==== Other Comments: ====
This is the working draft, there is still no code...

Querying API:

(document-create alist) -> integer or #f
(document-update identifier alist) -> boolean
(document-lookup field value) -> integer stream

(link-create identifier label other) -> boolean
(link-lookup identifier #:optional label) -> integer stream
(link-lookup-incoming identifier #:optional label) -> integer stream

CLI options:

--host                  default: 127.0.0.1
--port                  default: 8976
--home                  default: current directory
--workers               default: 2
--version               Show version.
-h --help               Show this message.
