I've started developing an environmentalist homepage here:
http://fecowebs.ourproject.orgDuring development, I've met with some legal questions, for example, I realized that it is not sure that I can use "deep linking". Now there is another legal question: can I put there a PDF file and share it as public domain?
At first, we might think yes. But if there's a font incorporated in the PDF file, and if that font is not public domain, I guess the PDF file cannot be in the public domain (otherwise the font could be extracted from it as public domain). Fortunately, I read that the PDF file format has some standard fonts which are not incorporated in the PDF file - I will probably use one of them or I will create a public domain font (which I want to do anyway).
But I'm still uncertain if I can share a PDF file as public domain: the PDF file format specification is not free (although licensed freely), and it is not clear to me whether a PDF file can be public domain while the PDF file specification is patented.
Can you show me free online lawyers, or legal texts which help environmentalists or my special case?
