The word "free" carried with it an inescapable moral connotation: Those were merely pleasant side effects of a motive that was, at its root, neither technical nor mercantile, but moral.

Furthermore, the "free as in freedom" position forced a glaring inconsistency on corporations who wanted to support particular free programs in one aspect of their business, but continue marketing proprietary software in others.

After the Netscape announcement broke in January I did a lot of thinking about the next phase -- the serious push to get "free software" accepted in the mainstream corporate world. And I realized we have a serious problem with "free software" itself.

Specifically, we have a problem with the term "free software", itself, not the concept. I've become convinced that the term has to go. Open Source: A Multidisciplinary Approach. Imperial College Press. Netscape Communications Corporation.

Archived from the original on Netscape Communications. This event marked a historical milestone for the Internet as Netscape became the first major commercial software company to open its source code, a trend that has since been followed by several other corporations.

Since the code was first published on the Internet, thousands of individuals and organizations have downloaded it and made hundreds of contributions to the software.

Free Software Foundation. Retrieved July 23, As the advocates of open source draw new users into our community, we free software activists have to work even more to bring the issue of freedom to those new users' attention.

We have to say, 'It's free software and it gives you freedom! Every time you say 'free software' rather than 'open source,' you help our campaign. Sooner or later these users will be invited to switch back to proprietary software for some practical advantage Countless companies seek to offer such temptation, and why would users decline? Only if they have learned to value the freedom free software gives them, for its own sake.

Open-source software

It is up to us to spread this idea—and in order to do that, we have to talk about freedom. A certain amount of the 'keep quiet' approach to business can be useful for the community, but we must have plenty of freedom talk too.

Under the pressure of the movie and record companies, software for individuals to use is increasingly designed specifically to restrict them. Their idea is that by publishing the source code of programs designed to restrict your access to encrypted media, and allowing others to change it, they will produce more powerful and reliable software for restricting users like you.

Then it will be delivered to you in devices that do not allow you to change it. This software might be 'open source,' and use the open source development model; but it won't be free software since it won't respect the freedom of the users that actually run it. If the open source development model succeeds in making this software more powerful and reliable for restricting you, that will make it even worse. Software Freedom and Intellectual Property Law".

Not only can they restrict document access but they also reliably enforce permissions in ways that the standard security handler does not.

The signature is used to validate that the permissions have been granted by a bona fide granting authority. For example, it can be used to allow a user: For example, Adobe Systems grants permissions to enable additional features in Adobe Reader, using public-key cryptography.

Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority. Any PDF application can use this same mechanism for its own purposes. PDF files can have file attachments which processors may access and open or save to a local filesystem. PDF files can contain two types of metadata.

This is stored in the optional Info trailer of the file. A small set of fields is defined, and can be extended with additional text values if required. This method is deprecated in PDF 2.

This allows metadata to be attached to any stream in the document, such as information about embedded illustrations, as well as the whole document attaching to the document catalog , using an extensible schema. PDFs may be encrypted so that a password is needed to view or edit the contents.

PDF 2. PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing or printing. These restrictions depend on the reader software to obey them, so the security they provide is limited. PDF documents can contain display settings, including the page display layout and zoom level.

Adobe Reader uses these settings to override the user's default settings when opening the document. Anyone may create applications that can read and write PDF files without having to pay royalties to Adobe Systems ; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.

PDF files can be created specifically to be accessible for disabled people. Some software can automatically produce tagged PDFs, but this feature is not always enabled by default. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges. One of the significant challenges with PDF accessibility is that PDF documents have three distinct views, which, depending on the document's creation, can be inconsistent with each other. The three views are i the physical view, ii the tags view, and iii the content view.

The physical view is displayed and printed what most people consider a PDF document.

The tags view is what screen readers and other assistive technologies use to deliver a high-quality navigation and reading experience to users with disabilities. The content view is based on the physical order of objects within the PDF's content stream and may be displayed by software that does not fully support the tags view, such as the Reflow feature in Adobe's Reader.

PDF attachments carrying viruses were first discovered in It was activated with Adobe Acrobat, but not with Acrobat Reader.

From time to time, new vulnerabilities are discovered in various versions of Adobe Reader, [56] prompting the company to issue security fixes. Other PDF readers are also susceptible. One aggravating factor is that a PDF reader can be configured to start automatically if a web page has an embedded PDF file, providing a vector for attack.

If a malicious web page contains an infected PDF file that takes advantage of a vulnerability in the PDF reader, the system may be compromised even if the browser is secure. Disabling JavaScript execution in the PDF reader can help mitigate such future exploits, although it does not protect against exploits in other parts of the PDF viewing software.

Security experts say that JavaScript is not essential for a PDF reader, and that the security benefit that comes from disabling JavaScript outweighs any compatibility issues caused. On March 30, security researcher Didier Stevens reported an Adobe Reader and Foxit Reader exploit that runs a malicious executable if the user allows it to launch when asked.

A PDF file is often a combination of vector graphics , text, and bitmap graphics. The basic types of content in a PDF are:. Two PDF files that look similar on a computer screen may be of very different sizes.

For example, a high resolution raster image takes more space than a low resolution one. Typically higher resolution is needed for printing documents than for displaying them on screen. Other things that may increase the size of a file is embedding full fonts, especially for Asiatic scripts, and storing text as graphics. PDF viewers are generally provided free of charge, and many versions are available from a variety of sources.

Raster image processors RIPs are used to convert PDF files into a raster format suitable for imaging onto paper and other media in printers, digital production presses and prepress in a process known as rasterisation. Adobe Acrobat is one example of proprietary software that allows the user to annotate, highlight, and add notes to already created PDF files. Freeware Qiqqa can create an annotation report that summarizes all the annotations and notes one has made across their library of PDFs.

There are also web annotation systems that support annotation in pdf and other documents formats. In cases where PDFs are expected to have all of the functionality of paper documents, ink annotation is required. Examples of PDF software as online services including Scribd for viewing and storing, Pdfvue for online editing, and Thinkfree , Zamzar for conversion. The company released an upgrade to their Harlequin RIP with the same capability in Agfa-Gevaert introduced and shipped Apogee, the first prepress workflow system based on PDF, in The Preview application can display PDF files, as can version 2.

The files are then exported in PDF 1. When taking a screenshot under Mac OS X versions The Free Software Foundation once thought of as one of their high priority projects to be "developing a free, high-quality and fully functional set of libraries and programs that implement the PDF file format and associated technologies to the ISO standard.
