- Link as links table row.
 - Link as gql relational schema.
 - Link as minilinks structure.
 
- Link by relation 
typereturns type link of current link. Current link is instance of type link. -  Type link behaves like a typing rule. Instance links must has 
from/toequal by type to typefrom/to. - If a typing violation is found, link insert transaction will be rolled back with a verbose error.
 
- Link may have 
valuefield with any custom structure. - How to custom tables.
 -  If link type have attached table, then row with link_id can be getted with 
valuerelation from that link. - Tables awailable independently as table, or as link relation, if you know table id.
 -  If 
Columnlink hasvalue: { value: 'abc' }, then column in database will have name = abc. 
- If your want search by tree ranges, you must define tree.
 - You can expand and decrease tree structure every time.
 - On client side, you can expand plain results into linked minilinks structure.
 -  Relations 
upanddown. 
- Built-in model of selecting data.
 - Usage for trees.
 
- Basical rule theory
 -  Actions 
insert/update/delete/selectfor permissions. - Custom actions.

- Package contain 
itemslist. Item is{ id type from to value }. - Field 
idcan be defined any unique for package string|number. Package id names/numbers - local id. - Field 
idin data base names global id. -  After package import, local id of currentLink stored in 
package |= contain => currentLinkincontain.value.value. - Fields 
from_id,to_id,type_idnot used in packages. - Links in package connected by fields 
from,to,type. - If only 
idandvalueis defined, buttypeand others not defined, item exists for insert value in specific order after base link byidalready inserted. - If 
package.strictis true, then items insert in strict order as in package. 
-  If inserted link has subscribed by type or selector handlers, then creates links 
thenandpromisein transacition.current |-- then --> promise. -  For answer - 
is link background handlers resolved?need to verify any one of this conditions:- if link not have outgoind 
|-- then -->links - else link has 
has,promiseandresolvedlinks as|-- then --> promise |-- resolved, but has notrejectedlinks as|-- then --> promise |-- resolved. - else if link has 
rejectedlinks (it doesn't matter if there is aresolvedor not), it means a link was inserted with unsuccessful reactions and is considered damaged in a general sense, but you can check eachrejectedandresolvedlinks from promise. This will allow you to understand which handlers are errored. 
 - if link not have outgoind 
 -  In js implementation you can use 
await awaitPromise({ id, client })method returns native promise. 
-  Mutation 
reserve({ count: 15 }) { ids }reserve some count of link ids and return it as ids. - You can insert links with ids from reserve mutation.
 - One hour from reservation - imeout for cleaning reserved ids.
 
Here will be hybric passportjs and deep jwt standart.
- Temporary 
guestgql query generate new link and jwt for it. - Temporary 
jwtgenerate new jwt from linkId.
