LAB 2 – ELDERS PRODUCT SPECITICATION 22
Introduction
There will be a great loss around the world in the next century. More than half the languages around the world will go extinct. With people speaking commonly used languages, people do not understand much about endangered languages. The endangerment of a language is similar to the endangerment of plants and species, but will result in the loss of the unique cultural, historical, and spiritual knowledge. The Cheroenhaka (Nottoway) Indian language happens to be one of the hundreds of languages that are listed as extinct.
With the Endangered Languages Documentation Extension and Revival System project, known as ELDERS, there will be great hope in the revival of the Nottoway language. The Indian Tribe was known as Cheroenhaka, but upon contact with the English (Colonials), the English called them Nottoway. The Nottoway had made first contact with the English back in 1608. They lived and hunted by the Nottoway and Blackwater rivers in the southeastern part of Virginia which is now known as Sussex County and Capron. Even though the Nottoway language is not spoken today, the language is still an important part of their culture.
The revival system will not only teach the Nottoway language, but it will expand the dictionary on new words voted by the tribe. The only documentation on some of the words was documented by Thomas Jefferson. There is very little known information about the language and no alphabet has been documented. The ELDERS project will consist of a free web-based system for anyone to use.
Purpose
With the ELDERS (Endangered Language Documentation Extension and Revival System) project, there will be the revival of the Nottoway language. It will focus on storing and preserving the original language along with new words with an online database with a GUI frontend. With it being free and online, this will help expand the language. We want to keep a user’s attention, which is why the games (learning activities) will provide an effective fun learning capability. With the goal being able to create new words, this would be most effective when the user learns more about the language.
Our methods are to encourage the use and expansion on the Nottoway language. This could also lead to other endangered languages revival. Only one step at a time needs to be taken and this is with the ELDERS project. There will much involvement with the Nottoway Indian tribe as the ELDERS project brings back the language culture for them.
The voting committee will consist of the council members and the chief. They will be the ones to vote what words will be included into the Expanded Dictionary.

General Description
The ELDERS prototype is capable of expanding and teaching the Nottoway language. The prototype will display the language and its dictionaries, activities for learning the language, history of the tribe, and a forum. The forum is a way to keep in touch with the new word submissions and words that have been voted into the expanded dictionary by the voting committee.
Overview
The following section will describe the specific functional, hardware, software, and external interface architecture, assumption, constraints, and non-functional requirements of the ELDERS project. The key features of the prototype; the parameters that will be used to control, manage, or establish these features.

Prototype Architecture Description
Figure 1. Prototype major functional component diagram.
The interface will contain the LAMP stack. The prototype will feature a virtual machine that will have MySQL database and Apache server. This can be accessed by a remote desktop client. Python will be the written coded algorithm for the ELDERS project. There will be two different algorithms based on the dictionaries and search engine. With the voting of new words, the database will see if the word is already contained in the dictionary. The community and the council members will vote on which words will be used in the expanded dictionary.
Prototype Functional Description
The database will have at least two tables that contain historic dictionary and expanded dictionary. With the historic dictionary, it will store the words that are currently known in the Nottoway language. No administrator will be able to change or mess with the words in the historic dictionary. This is to keep the original documented Nottoway words preserved. Inside the expanded dictionary it will contain the words from the historic dictionary along with new words that have been voted for by the voting committee. Users will be able to look how the old words are used and what they mean along with other Indian languages that are closely similar to the language. The council, a group from the Indian tribe, will vote on the new words that users will be creating. They have the final saying if the word should be added or not. If it is added, it goes within the expanded dictionary. The council will have administrator rights to be able to modify words from the list or if need be, remove words only in the expanded dictionary.
The ELDERS project is not just about creating lost words for the language. It is about reviving and expanding the culture of the language. That is why there is an educational part for the project that consists of the language and history lessons of the Nottoway tribe. The game section focuses on having the user enjoy learning the Nottoway language, with a choice of different games.
External Interfaces
External interfaces will be limited to standard PC hardware and software. The only custom interfaces will be the ELDERS website.
Hardware Interfaces
The hardware will consist of a client/server application. The client will be able to access anything on the server with a computer or mobile device that has access through the network. The server will have a minimal projected specifications 2-4 GB RAM and 20 GB of storage. Authentication will control accountability and limit roles and/or views of certain users. Users will be able to view the alphabet, old dictionary, new dictionary, historic background and communication methods.
Software Interfaces
This is a free access website with registered access. We want to use the LAMP (Linux, Apache HTTP server, MySQL, PHP) stack. Group members will interface with the MySQL databases using standard. PHP web pages will be developed using standard text editing tools.

User Interfaces
There will be a main interface accessed by any Internet-connected computer with a web browser. In the future, it will be accessed by a mobile device. The interface is the ELDERS website. This site will permit new users to register and allow existing users to maintain their ELDERS accounts.

These interfaces will provide a login screen as well as a user-specific home page which is presented after a successful authentication.
