OpenData is the Spanish Patent and Trademark Office's portal for the publication of public data. These data are generated in reusable form to enable third parties to use them through proprietary or derived services.
Opening public data consists of publishing the information held in the public sector to make it available to all citizens in a digital, standardised and open format, following a clear structure that enables data compression. At the same time, access to this information is facilitated to promote its reuse.
This provides society – citizens, businesses and any other institution – with easy access to it for information purposes or to create new services and increase its social and commercial value.read more
XML(eXtensible Markup Language) is an extensible markup language developed by the World Wide Web Consortium (W3C). It is a simplification and adaptation of SGML, and makes it possible to define the grammar of specific languages (in the same way that HTML is, in turn, a language defined by SGML). This means that XML is not really a specific language, but rather a manner of defining languages for different needs. Some of the languages that use XML for their definition are XHTML, SVG, MathML.
XML did not emerge solely to be applied on the Internet, rather it is proposed as a standard for the exchange of structured information between different platforms. It can be used in databases, text editors, spreadsheets and almost anything else imaginable.
XML is a simple technology with others around it with far greater possibilities that complement and significantly expand it. It plays a very important role today as it enables compatibility between systems for sharing information in a secure, reliable and easy way.
SGML stands for Standard Generalized Markup Language. It consists of a system for organising and marking up documents. The International Standards Organisation (ISO) standardised this language.
The SGML language is used to specify the markup rules for documents and does not, in and of itself, impose any particular set of tags.
The HTML language is defined in terms of SGML. XML is a standard that was created afterwards that incorporates a subset of SGML functionality (sufficient for common needs) and is much easier to implement as it avoids certain advanced SGML features.
The document publishing industry is one of the main users of the SGML language. Using this language, documents are created and maintained and then ported to other final formats such as HTML, PostScript, RTF, etc.
PDF (Portable Document Format) is a document storage format developed by Adobe Systems. It is a compound format (vector imaging, bitmaps and text).
It is specially designed for documents that can be printed because it specifies all the information necessary for the final presentation of the document, determining all details of its final appearance and without requiring prior adjustment or layout processes.
It is multi-platform, which means that it can be displayed by the leading operating systems (Windows, Unix/Linux or Mac) without modifying the appearance or structure of the original document.
It can accept any combination of text, multimedia elements (such as video and sound), hypertext elements (such as links and markers), hyperlinks and page miniatures.
It is one of the most extensively used formats on the Internet for exchanging documents. That is why it is used extensively by companies, governments and educational institutions.
It is an open specification for which freeware tools have been generated to create, view and modify documents in PDF format. An example of this is the OpenOffice.org office automation suite and the LaTeX text processor.
It can be encrypted to protect the content and even signed digitally.
