Abstract. This article purposes to present an authoring tool for learning objects 
(LOs) with metadata filling in the OBAA standard and SCORM packaging 
generated in scientific initiation research. The software, in early stage of 
development, is noted to be free and easy to use, programmed for the Web 
platform pointing towards features to enhance the user experience. The 
application is internationalized and has a repository function, which stores the 
LOs in a database accessed through the search feature. Its origin took place on 
the lack of tools making use of the characteristics applied to this one and its 
goal is to simplify, to the teacher, the creation of teaching materials, as well as 
encourage students to invent their own content. Therefore, a study was 
conducted of LOs, their metadata, specifications and related tools as well as of 
the technologies needed to create the system, such as concepts, languages and 
programming standards.  
Keywords: Learning Objects, OBAA, SCORM, e-learning. 
1   Introduction 
According to Wiley [1], Learning Objects (LOs) are digital educational content, 
whose basic feature is their ability to be used on other occasions. Thus, LOs are made 
up of texts, images or videos, for example, along with their metadata, which, together, 
form a reusable LO. The metadata are essential to the educational material since the 
repositories use them to catalog and store objects. To facilitate cataloging, several 
metadata specifications have been developed, such as IEEE LOM (international 
reference standard), CanCore (Canadian standard) and OBAA (Brazilian standard). 
To simplify the generation of LOs and their metadata, there have been developed 
some authoring tools. However, most of them present themselves complex, require 
computer skills or additional installation to be used, or, still, demand payment. Even 
so, there are few which allow the making of objects in the OBAA standard or make 
use of SCORM during the files packaging. 
The present research, conducted focusing on the relevant basic concepts and on the 
current situation of the subject, as well as on the technology needed to create the 
software, has been characterized as preparation for the construction phase, which 
601
generated a tool - at the time in early stage of development - of simple and easy 
procedure, that, besides standardizing the metadata description and LO packaging, 
requires only a web browser with Internet access to work. It was also sought to adapt 
the tool to different devices and internationalize it. It is expected, with its use, to 
facilitate the teacher’s task to create educational content, encourage students to invent 
their own materials and disseminate the OBAA model. 
This document is divided into four chapters. First there is an introductory text 
about the covered issues, followed by the Theoretical References appropriate to the 
research phase (split into Methodology Used, OBAA standard, SCORM standard and 
Authoring Tools). In third takes place the presentation of the proposed tool, with 
details about its project and development as well as examples of its current operating 
condition. Finally, it is concluded the article and elucidated how the project will be 
continued. 
2   Theoretical Reference  
2.1   Methodology Used 
Until the present moment, this work is based on qualitative research because it used 
bibliographic research approach in order to understand the concepts to be smeared on 
the tool. Next, this study turns into applied research since it aims its use in practice, 
involving future instructional designers as subjects. 
Initial research marks itself with online studies, in websites as well as in academic 
papers, aiming to understand the fundamental concepts connected to the project 
subject, such as the study of the PHP language and the theories and applications of 
learning objects (LOs) and their metadata. After, there has been a reading of Wiley's 
[1] and Silva's [2] works, which are widely cited in papers of their areas, in order to 
supplement the initial concepts notion. It has also been sought to understand the 
current situation of the tools and technologies available for the creation and 
maintenance of LOs. 
Following the initial research stage, it has been run a study of the languages and 
tools compulsory to the software creation (emphasis on PHP, JavaScript, CSS, 
HTML, Database/MySQL), and, from the model proposed by the mentor teacher, it 
was then given start to the development. Additionally, it has been adopted the OBAA 
standard of metadata descripting through XML files and the SCORM standard for file 
packaging. 
The following research steps aim to verify using it in the potential scenarios: 
descripting a LO, packing a LO, searching for a LO on the repository, etc. For that, it 
will be developed schedules which, when applied, it will be adopted non-participant 
observation, in order to register the interaction with the tool. Furthermore, it is 
possible to include a log record which will indicate how and when the users used the 
system, supplying quantitative and qualitative data. 
602
2.2   OBAA 
Knowing that a LO is any educational media that can be reused, OBAA has emerged 
as the Brazilian proposal for the educational and technical description of these objects 
through metadata, in order to facilitate their retrieval and access. The model, whose 
acronym translates to “Agent-Based Learning Objects”, was developed by UFRGS in 
partnership with UNISINOS, aiming to specify standards for technical and functional 
requirements in response to interoperability problems of some digital contents that, in 
short, were settled by the XML syntax typical of this standard [2]. 
OBAA was established in the IEEE LOM, an international reference standard 
extensively used which allowed some changes that were considered necessary for the 
creation of OBAA. Consequently, OBAA aggregated the LOM categories, applying 
modifications and adding new items [3]. 
2.3   SCORM 
SCORM (Sharable Content Object Reference Model) is a collection of specifications 
and standards which define the interrelationship of content objects and data models so 
that the objects are sharable on systems that follow this model [4]. This specification 
promotes reusability, accessibility, durability and interoperability of learning content, 
and facilitates migration between different learning management systems. SCORM is 
responsibility of Advanced Distributed Learning and was originally released in 2000, 
with the latest version being the SCORM 4th Edition, of 2009. 
Tarouco and Dutra [5] explain that resources (also called educational media) are 
the smallest physical units within the SCORM material. Examples include web pages, 
images, videos and flash applications. Its main feature is to be reusable, and for this to 
be possible, it is used the asset’s metadata. SCOs (Sharable Content Objects) are the 
sets of resources which represent the smallest logical units of the material: they can 
represent a class, a topic or a module in a course. SCOs cannot communicate among 
themselves because they are independent.  
2.3   Authoring Tools 
According to Leffa [6], the term authoring tool (AT) refers to a type of software 
which objectives to generate Learning Objects such as texts, images, videos, audios, 
among others. These tools are both offline or online and have as targeted audience 
students and teachers. The author states that the preference for these systems is due to 
their ability to offer a quick and easy way to create quality educational content, 
requiring only the input of knowledge and creativity. 
Among the advantages of ATs should be cited the high level of interaction the user 
is likely to have with the object – making learning easy –, and the low cost of material 
generation [6]. However, it is important to note that despite these advantages, the 
produced objects should not replace the teacher, but rather complement the work in 
the classroom. There are several ATs: ALOHA, Ardora, CourseLab, PALOMA and 
eXe-Learning, for instance. 
603
It is noteworthy, though, that most of those tools have hardware and/or software 
compatibility issues, require installation of additional applications, do not use the 
OBAA standard or are not free or user-friendly. 
3   Proposed Tool 
This document proposes an authoring tool for learning objects capable of generating 
educational content and its metadata in the OBAA format, and performing the 
packaging with the SCORM standard, as well as saving the created object in the tool’s 
own repository, conferring user’s wish. Its main characteristic is to differentiate itself 
from other applications for not requiring any kind of installation and being free, 
intuitive and easy to use. For this, the system takes advantage of the Web platform, 
being a prerequisite for its use just any web browser with Internet access. 
3.1   Project 
The tool here presented is intended to be a mixture of repository with authoring tool, 
presenting itself simple, easy to use and intuitive. For this, it has been pursued to take 
advantage of a clean and friendly interface as well as presenting the possibility to 
change language and the use of a feature which automatically adjusts the layout in 
accordance to the screen resolution. Consequently, the user should not spend too 
much time looking for where to click or trying to understand what must be done. 
Furthermore, by changing the layout, functions are released or hidden, avoiding, for 
example, that someone using the system in a mobile phone access, by mistake, the 
option of content creation, which requires text or image input, formatting... in short, a 
task that would rarely be accomplished through that type of device. 
Of the repository and authoring tool functions, the system comprises four 
independent components, which can be used singly or in combination, as the user 
wishes. Such divisions are detailed below. 
• Educational material making: the tool features an editor capable of performing 
content creation based on text and media (audio/video/image), the output of which 
is the metadata filling screen. The editor can be accessed through the main page on 
desktop computers and laptops. 
• OBAA metadata filling: following the use of the editor or directly through the 
home screen, for desktop computers and laptops, it is presented a metadata form 
according to the OBAA standard. The form handling performs the creation of the 
pertinent files and the packing in SCORM, and stores the object in the tool’s 
database. After submitting the form, the user will receive a ZIP file (the very 
Learning Object itself) via direct download and will be prompted whether to keep 
or not the object in the repository. 
• SCORM packaging: packaging occurs automatically after submitting the metadata 
form or, if the LO has been previously made, it can be accessed through the home 
screen on desktop computers, laptops or tablets. If the latter, it will be shown a 
screen where the user uploads his LO and the system converts it to SCORM 
604
format. In both cases, the LO will be saved in the repository and the user will be 
prompted if they want to keep it that way or remove it, in addition to receiving 
their packaged LO via direct download. 
• Search: to any device used, one can perform a search in the repository database 
from the main screen. For smartphones it is only possible to execute textual search, 
while for tablets, laptops and desktop computers it is possible to make use of a 
sliding menu of images, representing different themes-filters for search. The output 
is a screen showing the search results, with brief summaries of found LOs, link to 
details of each LO and filters to refine results. The details page is also ruled by the 
resolution of the device in use: mobile is only given the option to view the LO, 
while for the other devices one can download the LO without SCORM, with 
SCORM or simply view it. 
The prototype of screens and their relationships, as well as the overall class 
diagram, were proposed by the project’s mentor teacher, and then adapted as 
appropriate during the development process. 
3.2   Development 
The development process began with the study of needed languages and technologies: 
PHP, HTML, CSS, JavaScript and Database/MySQL; as well as Object Oriented 
Programming, Model-View-Controller and OBAA and SCORM standards. Next, 
from the model proposed by the mentor teacher, were developed the tool prototype 
layouts for the different devices and basic versions of the most significant pages, 
including: the form for the metadata descripting, the editor for creating the 
educational content and the home page with the sliding menu used to filter search and 
the textual search field. Consequent to it happened the database modeling and 
generating, followed by the construction of the PHP classes which would be 
responsible for the objects representing the metadata and for the translation function. 
It is emphasized here that all mentioned components suffered, constantly, changes to 
meet all specifications and unexpected errors. 
It has also been worked on the XML file, done through PHP’s DOMDocument 
class, which allows a XML file in accordance to the OBAA model. It is utilized the 
ZipArchive class as well, to compress the XML file along with the educational midia 
and the HTML page which references said midia. 
The SCORM components (and several other minor details) were not, yet, worked 
on as the tool is just in early stage of development. 
3.2   The Tool Working 
In the tool’s current version, considered by the authors as early stage of development, 
are presented, fully operative, the following features (already termed in previous 
sections): metadata form with XML file generation, creation of educational content 
through a basic editor, storage in the database, search from textual terms and 
translation and automatic layout change functionalities. 
 
605
  
Figures 1 and 2 illustrate the operation of the tool here shown. Figure 1 shows the 
main screen with the search system and three buttons: one for each function of the 
tool. In Figure 2 it can be seen the form for metadata filling as the OBAA standard.

4   Conclusion 
Though little known, the learning objects (LOs) have become popular and necessary, 
perpetrating imperative the presence of tools to assist in their creation, maintenance 
and dissemination. Even more important is the existence of applications capable of 
generating objects in accordance with the Brazilian standard, in order to encourage 
and disseminate its culture. 
With the main features - such as searching for objects from the repository, creating 
LOs with the editor and inserting objects in the database with the metadata cataloging 
- already operating, it is tangible that the proposed system, even in early stage of 
development, meets the accentuated profile. 
Next, it is expected to improve the search function with filters and perform the LO 
conversion to SCORM. It is planned to, in the future, improve the LOs editor and the 
system layout.
