Problem: Given the question: Information: - The First Crusade (10951099) was the first of a number of crusades that attempted to capture the Holy Land, called by Pope Urban II in 1095. It started as a widespread pilgrimage in western Christendom and ended as a military expedition by Roman Catholic Europe to regain the Holy Land taken in the Muslim conquests of the Levant (632661), ultimately resulting in the capture of Jerusalem in 1099. - The Crusade of 1101 was a minor crusade of three separate movements, organized in 1100 and 1101 in the successful aftermath of the First Crusade. It is also called the Crusade of the Faint-Hearted due to the number of participants who joined this crusade after having turned back from the First Crusade. - Ida of Austria ( c. 1055 -- September 1101 ) was a consort of Leopold II of Austria . She was a crusader , participating in the Crusade of 1101 with her own army . What entity does 'ida of formbach-ratelnberg' has the relation 'date of birth' with?

Problem: Given the question: Information: - The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, which promotes the universal freedom to study, distribute, create, and modify computer software, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Massachusetts, USA, where it is also based. - Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software. That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users. - Linus Benedict Torvalds (born December 28, 1969) is a Finnish software engineer who is the creator and, for a long time, principal developer, of the Linux kernel; which became the kernel for operating systems such as the Linux operating system, Android and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award. - OpenSceneGraph is an open source 3D graphics application programming interface, used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization and modeling. - Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. - A scene graph is a general data structure commonly used by vector-based graphics editing applications and modern computer games, which arranges the logical and often (but not necessarily) spatial representation of a graphical scene. Examples of such programs include Acrobat 3D, Adobe Illustrator, AutoCAD, CorelDRAW, OpenSceneGraph, OpenSG, VRML97, X3D, Hoops and Open Inventor. - Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. According to scientists who studied it, open-source software is a prominent example of open collaboration. - Open Inventor, originally IRIS Inventor, is a C++ object oriented retained mode 3D graphics toolkit designed by SGI to provide a higher layer of programming for OpenGL. Its main goals are better programmer convenience and efficiency. Open Inventor is free and open-source software, subject to the requirements of the GNU Lesser General Public License (LGPL), version 2.1. Early in development (in 1991) a group of developer split off to develop OpenGL Performer with the different goal of making the program fast. - GNU is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own GPL. - OpenSG is a scene graph system to create real - time graphics programs , e.g. for virtual reality applications . It is developed following Open Source principles , LGPL licensed , and can be used freely . It runs on Windows , Linux , Solaris and OS X and is based on OpenGL . Its main features are advanced multithreading and clustering support ( with sort - first and sort - last rendering , amongst other techniques ) , although it is perfectly usable in a single - threaded single - system application as well . It is not part of Khronos Group . What entity does 'opensg' has the relation 'license' with?
