ABSTRACT
The possibility of using Open Source-technology as an inurnment of creation the syflem of informative cooperation during the project support in aerospace induflry is under consideration. Information web-portal provides the access for this informative cooperation. In order to develop the information portal the specialized management syflems for CMS content with open source code are fludied.
АННОТАЦИЯ
Рассматривается возможность применения Open Source-технологий как инструмент создания системы информационного взаимодействия при сопровождении проектов в аэрокосмической отрасли, доступ к которому обеспечит информационный веб-портал. Для разработки информационного портала изучены специализированные системы управления контентом CMS с открытым исходным кодом.
Keywords: open source, cms, content management syflem, open source code.
Ключевые слова: open source, cms, системы управления контентом, открытый исходный код.
The use of Open Source-technology is the mofl significant innovation in the approach of the creating an information support syflem for project management in aerospace induflry. Currently, Open Source software is one of the mofl popular free software with open source code. Open Source gives great opportunities, allows to save finance and to accelerate work processes, as opposed to the commercial software that has closed access to the source code. Commercial software does not give an opportunity to improve and adjufl the software to fit your needs. So, since 2012, the National Aeronautic and Space Adminiflration in USA (NASA) has considered a new policy for the use of Open Source-technology for their developments. As it is known that NASA maintains a website called code.nasa.gov, which is the central repository for open source-development, and publish in open access on service Github for open source-users of scientific and practical developments [6]. It should be noted, that NASA has prepared a web-application for visualization of significant moments of their space program to the three-year anniversary of landing of Mars rover Curiosity [5].
The term "open source software" is the marketing name of free software that is created by the community Open Source Initiative (www.opensource.org). One of the overarching goals of the organization Open Source Initiative is the fight againfl negative flereotypes about the free software, and the promotion idea of diflribution of the source code [4, p.23]. The source code for these programs is available for viewing, fludying and changing. Primary advantages of Open Source are as follows:
- The basic package of any solution with open source code can be changed depending on current requirements and tasks regardless of vendor (supplier-manufacturer software);
- Open Source software can be integrated with other software by quickly setting up an IT-syflem;
- Quite a good level of protection and of information security;
-High adaptability of the syflem to any projects through the
open source code.
Presently, it is an acute problem of information support for monitoring projects of varying complexity and purpose. So Open Source-technology can be used for creating an integrated environment of information cooperation (IEIC) in the space induflry. IEIC will help to solve the problems of information
type, which frequently appear in the project organizations, namely:
1) Disparate information flow inside the company;
2) Disparate information flow from cuflomers, executors, service (product) contractors, etc.;
3) Different data from the various organization that use different software which are not integrated into a single database.
IEIC will allow analyzing, managing and monitoring the current flatus of the project, which will provide access by an information web-portal. Therefore, to develop the information portal, we will consider specialized Content Management Syflem (CMS) with open source code. CMS simplifies information content for Web application and allows a user to manage text and graphic content of web-portal. The main advantages of CMS:
1) Centralized management by a client-server base;
2) The ability to work from any web browser, regardless of a syflem and different platforms;
3) Multimedia content (HTML, XML, PDF, MP3, DOC etc.) management;
4) The ability to integrate various JavaScript-frameworks;
5) Content includes different modules;
6) Multilanguage support;
7) The absence of reflrictions on the development of accessible web-design.
Nowadays, the mofl popular CMS with the open source code are WordPress, Drupal and Joomla.
Wordpress is developed in a PHP programming language with a MySQL database. Wordpress is easy to underfland and to use, but not enough for implementation of the necessary tasks, because it is more suitable for blogging, although CMS's developers say about the possibility to use Wordpress for a wide range of tasks. It has a simple page layout, which consifls of three main parts: a header, a footer and a main body. It also has a built-in navigation syflem, which automatically generates a new connection when creating a new page [1, p.130]. Bearing in mind the fact that Wordpress is more suited for blogging and creating a website for a small business, the CMS will not be considered any further.
Drupal - content management syflem written by PHP and is used as a data flore relational database MySQL and PoflgreSQL. Drupal's architecture allows a user to use it for blogs, news
sites, news archives or social networks. The functionality, which is available by default, can be increased by using additional extensions - modules [3, p.15].
Joomla is a content management syflem written by PHP and JavaScript, and uses as a database Sore MySQL database. CMS
Joomla includes a minimal set of tools during setup, which can be added as needed. Joomla as Drupal can be used for creating blogs, news sites, news archives, social networks, etc.
Table 1 describes the main specifications of Joomla and Drupal [2, p.13].

Wordpress is not suitable for the development of information portal, because his platform does not have the necessary tools. Joomla and Drupal are multifunctional platforms, they are used all over the world for creating websites of any shapes and size. However, Drupal focuses on web-developers and demands a technical awareness of users. Consequently, a website development needs the time, and physical and material cofls. Joomla is simple with comfortable adminiflration interface provides comprehensive facilities (like Drupal). Therefore, CMS Joomla will be used to develop the information portal.
