Metadata Editor

Metadata Editor

Screenshot: Metadata Editor

Every resource in docendo has a dedicated metadata record assigned to it. The type of data assembled in the metadata record are defined by an IEEE Standard called Learning Object Metadata or just LOM. In the external links section you will find references to the standard's specification documents.

Some of the values in the metadata are fixed and cannot be changed, most notably identifier values which docendo internally uses for references between resources. Other values are created and filled in automatically, depending on the context the resource has been created in. For example your user profile information is used to create VCard values for “contribution” entries that identify you as creator of the resource.

The sections below explain the different categories of the metadata editor.

The metadata fields Title, Description and Keyword from the General category are being stored in docendo's search index and thus are very import to be filled in properly to get good results when searching for resources. For this reason, these 3 fields are presented separately on the resource editors.

Category: General

LOM category: General

Name Explanation Example
Identifier A globally unique label that identifies this learning object. -
Catalog The name or designator of the identification or cataloging scheme for this entry. A namespace scheme. “ISBN”, “ARIADNE”, “URI
Entry The value of the identifier within the identification or cataloging scheme that designates or identifies this learning object. A namespace specific string. “2-7342-0318”, “LEAO875”, “http://www.ieee.org/documents/1234
Title Name given to this learning object. (“en”, “The life and works of Leonardo da Vinci”)
Language The primary human language or languages used within this learning object to communicate to the intended user. NOTE 1:–An indexation or cataloging tool may provide a useful default. NOTE 2:–If the learning object had no lingual content (as in the case of a picture of the Mona Lisa, for example), then the appropriate value for this data element would be “none”. NOTE 3:–This data element concerns the language of the learning object. Data element 3.4:Meta-Metadata.Language concerns the language of the metadata instance. “en”, “en-GB”, “de”, “fr-CA”, “it” “grc” (ancient greek, until 1453) “en-US-philadelphia” “eng-GB-cockney” “map-PG-buin” (Austronesian –Papua New Guinea – buin) “gem-US-pennsylvania”
Description A textual description of the content of this learning object. NOTE:–This description need not be in language and terms appropriate for the users of the learning object being described. The description should be in language and terms appropriate for those that decide whether or not the learning object being described is appropriate and relevant for the users. (“en”, “In this video clip, the life and works of Leonardo da Vinci are briefly presented. The focus is on his artistic production, most notably the Mona Lisa.”)
Keyword A keyword or phrase describing the topic of this learning object. This data element should not be used for characteristics that can be described by other data elements. (“en”, “Mona Lisa”)
Coverage The time, culture, geography or region to which this learning object applies. The extent or scope of the content of the learning object. Coverage will typically include spatial location (a place name or geographic coordinates), temporal period (a period label, date, or date range) or jurisdiction (such as a named administrative entity). Recommended best practice is to select a value from a controlled vocabulary (for example, the Thesaurus of Geographic Names [TGN]) and that, where appropriate, named places or time periods be used in preference to numeric identifiers such as sets of coordinates or date ranges. NOTE 1:–This is the definition from the Dublin Core Metadata Element Set, version 1.14 . (“en”, “16th century France”) NOTE 2:–A learning object could be about farming in 16th century France: in that case, its subject can be described with 1.5:General.Keyword=(“en”,”farming”) and its 1.6:General.Coverage can be (“en”,”16th century France”).
Structure Underlying organizational structure of this learning object. NOTE:–A learning object with Structure=“atomic” will typically have 1.8:General.AggregationLevel=1. A learning object with Structure=“collection”, “linear”, “hierarchical” or “networked” will typically have 1.8:General.AggregationLevel=2, 3 or 4.
Aggregation Level The functional granularity of this learning object. If the learning object is a digital picture of the Mona Lisa, 1.7:General.Structure=Atomic and 1.8:General.AggregationLevel=1. If the learning object is a lesson with the digital picture of the Mona Lisa, 1.7:General.Structure=Collection or Networked (since there are two descriptions of the same type of Structure) and 1.8:General.AggregationLevel=2. If the learning object is a course on the Mona Lisa, 1.7:General.Structure=Linear if the documents are intended to be viewed linearly and 1.8:General.AggregationLevel=3. If the learning object is a collection of lessons on the Mona Lisa from different sources, 1.7:General.Structure=Collection and 1.8:General:AggregationLevel=3. Lastly if the learning object is a set of courses with a full history, description, interpretation, etc. of the Mona Lisa, 1.7:General.Structure=Linear or Hierarchical and 1.8:General.AggregationLevel=4. NOTE 2:–A learning object with AggregationLevel=1 will typically have 1.7:General.Structure=“atomic”. A learning object with AggregationLevel=2, 3 or 4 will typically have 1.7:General.Structure= “collection”, “linear”, “hierarchical” or “networked”.

LOM category: Educational

Name Explanation Example
Interactivity Type Predominant mode of learning supported by this learning object. “Active” learning (e.g., learning by doing) is supported by content that directly induces productive action by the learner. An active learning object prompts the learner for semantically meaningful input or for some other kind of productive action or decision, not necessarily performed within the learning object's framework. Active documents include simulations, questionnaires, and exercises. “Expositive” learning (e.g., passive learning) occurs when the learner's job mainly consists of absorbing the content exposed to him (generally through text, images or sound). An expositive learning object displays information but does not prompt the learner for any semantically meaningful input. Expositive documents include essays, video clips, all kinds of graphical material, and hypertext documents. When a learning object blends the active and expositive interactivity types, then its interactivity type is “mixed”. NOTE:–Activating links to navigate in hypertext documents is not considered to be a productive action. active documents (with learner's action): • simulation (manipulates, controls or enters data or parameters); • questionnaire (chooses or writes answers); • exercise (finds solution); • problem statement (writes solution). expositive documents (with learner's action): • hypertext document (reads, navigates); • video (views, rewinds, starts, stops); • graphical material (views); • audio material (listens, rewinds, starts, stops). mixed document: • hypermedia document with embedded simulation applet.
Learning Resource Type Specific kind of learning object. The most dominant kind shall be first. NOTE:–The vocabulary terms are defined as in the OED:1989 and as used by educational communities of practice. -
Interactivity Level The degree of interactivity characterizing this learning object. Interactivity in this context refers to the degree to which the learner can influence the aspect or behavior of the learning object . NOTE 1:–Inherently, this scale is meaningful within the context of a community of practice. NOTE 2:–Learning objects with 5.1:Educational.InteractivityType=“active” may have a high interactivity level (e.g., a simulation environment endowed with many controls) or a low interactivity level (e.g., a written set of instructions that solicit an activity). Learning objects with 5.1:Educational.InteractivityType=“expositive” may have a low interactivity level (e.g., a piece of linear, narrative text produced with a standard word processor) or a medium to high interactivity level (e.g., a sophisticated hyperdocument, with many internal links and views).
Semantic Density The degree of conciseness of a learning object. The semantic density of a learning object may be estimated in terms of its size, span, or –in the case of self-timed resources such as audio or video–duration. The semantic density of a learning object is independent of its difficulty. It is best illustrated with examples of expositive material, although it can be used with active resources as well. NOTE 1:–Inherently, this scale is meaningful within the context of a community of practice. Active documents: user interface of a simulation • low semantic density: a screen filled up with explanatory text, a picture of a combustion engine, and a single button labeled “Click here to continue” • high semantic density: screen with short text, same picture, and three buttons labeled “Change compression ratio”, “Change octane index”, “Change ignition point advance” Expositive documents: • medium difficulty text document o medium semantic density: “The class of Marsupial animals comprises a number of relatively primitive mammals. They are endowed with a short placentation, after which they give birth to a larva. The larva thereafter takes refuge in the mother's marsupium, where it settles to finish its complete development.” o high semantic density: “Marsupials are primitive mammals, with short placentation followed by the birth of larva, which thereafter takes refuge in the marsupium to finish its development.”
Intended End User Role Principal user(s) for which this learning object was designed, most dominant first. NOTE 1:–A learner works with a learning object in order to learn something. An author creates or publishes a learning object. A manager manages the delivery of this learning object, e.g., a university or college. The document for a manager is typically a curriculum. NOTE 2:–In order to describe the intended end user role through the skills the user is intended to master, or the tasks he or she is intended to be able to accomplish, the category 9:Classification can be used. An authoring tool that produces pedagogical material is a typical example of a learning object whose intended end user is an author
Context The principal environment within which the learning and use of this learning object is intended to take place. NOTE:–Suggested good practice is to use one of the values of the value space and to use an additional instance of this data element for further refinement, as in (“LOMv1.0”,”higher education”) and (“http://www.ond.vlaanderen.be/ onderwijsinvlaanderen/Default.htm” , “kandidatuursonderwijs”) -
Typical Age Range Age of the typical intended user. This data element shall refer to developmental age, if that would be different from chronological age. NOTE 1:–The age of the learner is important for finding learning objects, especially for school age learners and their teachers. When applicable, the string should be formatted as minimum age-maximum age or minimum age-. (NOTE:–This is a compromise between adding three component elements (minimum age, maximum age, and description) and having just a free text field.) NOTE 2:–Alternative schemes for what this data element tries to cover (such as various reading age or reading level schemes, IQ's or developmental age measures) should be represented through the 9:Classification category. “7-9”, “0-5”, “15”, “18-”, (“en”,”suitable for children over 7”), (“en”,”adults only”)
Difficulty How hard it is to work with or through this learning object for the typical intended target audience. NOTE:–The ” typical target audience” can be characterized by data elements 5.6:Educational.Context and 5.7:Educational.TypicalAgeRange. -
Typical Learning Time Approximate or typical time it takes to work with or through this learning object for the typical intended target audience. NOTE:–The ” typical target audience” can be characterized by data elements 5.6:Educational.Context and 5.7:Educational.TypicalAgeRange. “PT1H30M”, “PT1M45S”
Description Comments on how this learning object is to be used. (“en”, “Teacher guidelines that come with a textbook.”)
Language The human language used by the typical intended user of this learning object. “en”, “en-GB”, “de”, “fr-CA”, “it” NOTE:–As an example, for a learning object in French, intended for English-speaking students, the value of 1.3:General.Language will be French, and the value of 5.11:Educational.Language will be English.
