 lib used for:
-* file json manipulation: fs-extra.js
+- file json manipulation: fs-extra.js
 - templating szysteme: mustache.js
 - encryption with simple hash : bcrypt that is more efficient than crypto-js that is use inside a browser or node for cypher and uncipher
 - time management use luxon and no more moment 
-* cross domain management: cors.js
+- cross domain management: cors.js
-* to generate unique id use lib uuid.v4()

-* stripe to allow payment in $,€,... any device

 In general try to not install other lib in your dev. An apXtrib town mayor have to globaly valid to add a new lib into apxtrib so if you do then you can only use your town to provide your service and cannot use other town to deal wwith.

+### Object organization
+
+Object properties are strongly inspire of  https://schema.org/docs/schemas.html
+Fom https://json-schema.org/learn/
+    https://json-schema.org/understanding-json-schema/index.html
+    https://json-schema.org/draft/2020-12/release-notes.html
+Warning: stay in those specification much as it is possible, try to use existing object like person, organisation, ....
+As it is still on draft, a Odmdb.js (Objectdatamodeldatabase) is managing any CRUD on json object
+Any apxtrib key word is prefix by apx to inform that it does not exist in JSON schema protocole. This can be change in the futur if json schema will be stable enough.
+
+An **object is defined by a schema** store into ./nationchains/socialworld/schema/objectName.json or tribe/tribeId/plugins/pluginName/schema/objectName.json
+It lists key definition of an item's object.
+Items object are store into ./nationchains/socialworld/objects/objectName/objectNameid.json or tribe/tribeId/objects/objectName/objectNameid.json
+If an **item have a language** properties:lang that describe in with language is used by this item. If the object item cannot be translate this means that it is a different object.
+
+apXtrib **convention to manage language** to get a schema in a language:lg :
+|objectName|keyword => file ./nationchains/socialworld/objects_lang/objectName_lg.json = {keyword:description in lg}
+or tribe/tribeId/objects_lang/objectName_lg.json
+
+If any string start with | mean it exist a file translation
+
+A models/objectName.js manage all items of an objectName:
+    - CRUD action on any items depind of pagan accessright
+    - index builder that are store into /objectName/searchindex/
+       a searchindex file is named as objectname_idfield1_idfiled2_lg.json 
+       and contain: { value1idfiled1:[ value1idfield2 ] }
+       Depending of volume, it is possible to have objectName_UUID_UUID_lg.json this contain 
+       { valueuuid: { key:value of object} }
+
+
+#### Object key description
+
+Main properties key:
+* **description** a short description that can be use in GUI
+* **desclong** a long description
+* **info** a long or short html description
+* **default** value by default if not set when object is save, this can be a function 
+   example: UUID.v4()  or moment(new Date()).format('YYYY-MM-DD')
+* **format** usefull for date or any text structured  example:"YYYY-MM-DD"
+* **type** string / int / 
+* **enum**  list of valid data
+* **$apxenumkey**  if "data" then properties status.data has to be set as a {key:value}
+                   else a web link (absolute http:/... or relative ./...) to a {key:value} 
+                   mean the value have to be one of the key of this json file if it is required
