Populate word document with default metadata information

Question

Problem is revers as it is available in internet.  I have created list and
 columns. Which are populated  with default value. I have created word
 template. I can enter  data related to “Document properties”, ect. When I save that document to document library, I can see that filed data, that I type it in newly created word document.
But because I have several project document library and sites, I would like to create library, 
and fill all data with required values.  Then when I open new document from pre defied 
template, I would like to have all fields  that are empty in document, to be filed 
from  default columns value. Problem is, that when I save document, All fields are empty.
There is no problem, upending document, and default properties are presented.
How can I merge  default values from library, to word document ?

Answer 1

I have word template, that I added-it as a site content type. It has all standard 
fields  that are mapped to document library filed. If I open 
new document in  document library, and input 
required filed,  after  saving document, I can 
see those fields in SharePoint document library (Item properties).
Problem that I have is, following :
When I open that  document “new document” from template, I would like to have all fields filed with default values of that particular library.
Reason : Because  I will generate  hundred project (
Each new library is based on new project, build fields are the same, values changes to mimic project)
),  I do not wont to create additional template, that would have required fields fill up wit project value, and add it to content type.. .
I do not won`t to fill those properties manually.
Option 1 :  After saving document based on template, it will fill out  
required fields.
Option 2: Create template, for each project, and save that template as project template, that users open, and save it to project Site/library.
Option 1, is preferred.  Can that be done, when item is created, and copy project 
information, from different location ?
So I have  document library fields :
Name of the project,  Projec Manager,  Project ref number, Contract, ...
These filed are mapped to document filed :
Name of the project,  Projec Manager,  Project ref number, Contract, ...
I have document library : Project A
Project A  ,  John dear, 
REF2014_01_01, C1243332_2014, ...
I have document library : Project B
Project B ,  Same Jones ,  REF2014_03_05, AS563332_2014, ...
I would like,  that when I save  document
 using New document (template),  that have those filed fill up. I do not wont to 
create  new template for every project.
