This post will develop the following topics
- The problems of digital documents
- The PDF / A
- Requirement of PDF / A in the filing of certain documents
- lawful and free tools to package files in PDF / A
- control of PDF / A
We are in a transition period in which increasingly replace the documents "on paper" with digital documents.
There are many reasons to name but a few:
There are many reasons to name but a few:
- low cost compared to the costs of paper
- Significant reduction in storage space
- upgradeability and faster sharing of data can be sent
- complex documents and large via a WEB low costs and in real time.
to these great benefits, however, is a (possible) problem, that of long-term storage of these data.
The duration of the written data ... on paper is equal to the length of the paper.
In our libraries we can see, they are valuable historical documents, account books of the thirteenth century. In fact it was during this period that the cheapest paper in the West replaced the expensive parchment.
now arises the question, but until I can see my precious files?
The answer is not easy because it depends:
I nvece for the software aspect , to ensure the availability of software Idone or open the document even after many years , the project was initiated for PDF / A
2. The PDF / A
to ensure the availability of long-term data have been taken several initiatives, one that is getting more success is linked to the PDF / A, an international standard (ISO19005), subset of the standard PDF specially designed for storing long- period of electronic documents.
Portable Document Format, commonly abbreviated co PDF is a file format -based page description language developed by Adobe Systems in 1993 for ra ppresentare documents independently from ' hardware and software used to generate them or to see them.
In other words, can I get a PDF file from any application (Word, Writer, Calc, Excel, Power Point, AutoCAD, etc..) Substantially as an evolution of the "print to file".
A PDF file can describe documents containing text and / or images at any resolution. It is an open format, meaning that anyone can create applications that read and write PDF files without the payment of fees (royalties) to the Adobe Systems.
Adobe has a large number of patents relating to the PDF format but do not include the associated licensing fees for the creation of associated programs.
The PDF document does not include information specific to software, hardware and operating system used. This allows the document to be viewed and printed in the exact same way regardless of the platform and / or device used to read it.
This fact has helped to make it a de facto standard format widely used for sharing documents.
The only problem for printing documents in formato.PDF "normal" may arise from the use of local characters (eg Italian accented vowels), and if those who press their PC set to a language different.
The PDF / A has been developed to define an international standard Portable Document Format (PDF) for archiving and preservation of documents.
This standard has, to date, two levels of compliance:
Basically this format "encapsulates" all the necessary information in the file, ensuring that documents are fully self-contained. " All the information necessary to display the document are embedded in the document. This includes all content (text, raster images and vector graphics), fonts, colors and information.
I have a standard reader software and free, such as Acrobat (or Adobe e) Reader.
In relation to this software I take this opportunity to recommend the use of the latest version designed for your operating system.
You can verify this aspect of theAdobe to the official page at this address:

E 'should be specified that this format has two disadvantages:
3. Requirement of PDF / A in the deposit of some
documents are more and more governments and organizations that require this format to be submitted in digital documents such as the University for the thesis.
addition, to remain in an area common to us, from January 15, 2009 must be produced in PDF / A (exactly PDF/A-1b) all electronic documents supporting acts for which the law requires the publication by registration or filing in the Companies Register .
4. Tools lawful and free for package files in PDF / A
As mentioned earlier we can get this size by converting the file originated by various applications.
is a special "print to file", various software provide this option in the folder "Printers" computer, while others make it available usually defined command "Export to PDF"
To have these capabilities are available various software, some are valuable tools for a fee, but hereafter I will deal solely with the possibility of obtaining the desired result with applications lawful and free use . If interested
Open Office 4.1
As above video presented by an excellent solution for legal and free OpenOffice is , from version 2.4 (strongly recommended 3.0 or higher for most of the extensive management of PDF files). OpenOffice is a free download from the website:
http://it.openoffice.org/
we can produce a PDF / A from a document created with this software or imported from other compatible software (eg size. Doc) with the following steps:
1) Open the text document on the document drawn up with their instruments

The document was saved (with extension. Pdf) will be in PDF / A.
OpenOffice using the product, since version 3.0, and download them for free, you can also manage export to PDF / A document imported from scanners or already available in pdf "normal"
E 'must download and install Sun PDF Import, an add-on for OpenOffice can import and edit all documents in PDF format, to download using the following link:
http://extensions.services.openoffice.org/project/pdfimport
Among the potential free this extension allows you to capture an image from scanner and export it to PDF / A with the following steps:

3) Operate the choice Image , from Scanner
4) Click Start

8 ) Activate the Export
9) Save the document with the name chosen
This extension also allows you to open and edit (write, edit ...) files in PDF format is very convenient and above all free.
4.2 Installing a virtual printer
It 'still can also use a virtual printer by which "print to PDF" from any application you have installed on your computer.
There are many solutions, both free and fee. In the field of free software use is particularly interesting PDF Creator of PDF Forge.
E 'must have version 0.9.8 or later, using Ghostscript 8.64 to produce PDF files.
The software can be downloaded for free at
http://www.pdfforge.org/
This software allows a high level of management of the document in PDF format, to the best of our interest we must have the warning - When the window appears requesting the name of the file to be saved - choose the PDF / A from the dropdown list of formats.
For fans of computer you can operate directly installing Ghostscript 8.64,
downloaded from:
http://pages.cs.wisc.edu/ ~ ghost/doc/GPL/gpl864.htm
But this a mode more challenging installation by the user policy.
5. Control of PDF / A
Unfortunately there are currently no open source products can provide a reliable control of PDF / A.
There are thus provided for a fee, see on this site:
http://www.pdfa.org/
section Validate PDF / A
Among the commercial products used should be noted:
1) Open Acrobat Reader 9.0 or later
2) from the Edit menu and select Preferences
3) verify / set the ' option will display the documents in PDF / A with the value Only for PDF / A (usually in default installation).
open a PDF document with Acrobat Reader 9 can appear automatically, to top, a blue bar with the information "the document is displayed in PDF / A" .
If there is no such endorsement, certainly the format of the document does not comply standard PDF / A .
If you see the words indicated, the document format should be compatible with the standard PDF / A, but the certainty of the format can be determined with certainty only with the tools listed first.
The duration of the written data ... on paper is equal to the length of the paper.
In our libraries we can see, they are valuable historical documents, account books of the thirteenth century. In fact it was during this period that the cheapest paper in the West replaced the expensive parchment.
now arises the question, but until I can see my precious files?
The answer is not easy because it depends:
- By the time the media (Floppy, CD, DVD). It is not easy to provide data because of the relative youth of all existing media, but certainly it is not a very long duration, such as the manufacturers claim a life of 100 CD years, but we have many cases of lost data on CD (for decay of the substrate) after 10 years.
- From the continuous availability of the special player. To read a document of paper than I will need glasses, but to read a file I need to have CD / DVD, Floppy, Card Reader etc.. But in computer formats change. If at the time you save precious data on a floppy size of 5.25, on a Jaz disk, a tape Ditto Max, on a cartridge Sparq ... you will not find players to extract the dati.Se you're curious about the format obsolete reference to this Page
- Since availability of the appropriate software to read that particular file . The software is evolving, the software houses are closing or are absorbed, operating systems ... change outdated information and old files are no longer open because it lacks the appropriate software. Britain's National Archive has estimated to be in possession of a quantity of information - usually no more informed readable - that they can fill 580mila encyclopaedias!
I nvece for the software aspect , to ensure the availability of software Idone or open the document even after many years , the project was initiated for PDF / A

E 'should be specified that this format has two disadvantages:
- As a PDF / A should include all the fonts you use, a PDF / A will be equivalent large PDF file that does not include fonts.
- The majority of tools that allow the generation of PDF compliance with the standard PDF / A, as the PDF export tool in the suite Microsoft Office 2007 will eliminate the transparency of each image in document because this feature is prohibited in PDF/A-1.

3. Requirement of PDF / A in the deposit of some
documents are more and more governments and organizations that require this format to be submitted in digital documents such as the University for the thesis.
