Creating Records for the
Digital Library for Earth System
Education
11-12 February 2002
1
Today’s Goals
The basics of metadata, cataloging protocol,
vocabularies, best practices
Using the DLESE Resource Cataloger to a
create record
2
Metadata for DLESE
“Data about data” in the library will help
instructors & learners find what they need
Structured, descriptive information about a resource.
What is it about?
Who created it?
Where do I find it?
What do I need to use it? etc…
Information returned to user in a search
Information shared with other libraries
DLESE creates and holds metadata records, not the
physical files of resources
3
DLESE Metadata Framework
Full framework is extensive; > 100 fields
Some fields still under development
Currently, loosely based on IMS Standard
Collaboration in progress with NASA and
Alexandria Digital Library will evolve into a
joint XML schema-based framework (ADN).
Is saved as XML files; similar to HTML; but
has user defined tags
4
Required Metadata
Minimal metadata set to to identify the
resource
Provides descriptive, educational and
computer information as well as subject
assignment for browsing and assessment.
All records must contain this information
5
Required Metadata Fields
URL, Title
Description, Subject
Resource type, Audience
Technical info, Cost, Copyright
Resource creator
Resource cataloger (you)
6
Additional Optional Fields
Geospatial coverage
Relation
Annotation
Keywords
Science standards
Geography standards
7
Cataloging Process
Make informed decisions about content, pedagogy,
and computer requirements based on best practices
and cataloger expertise
From experience, spend 30 to 60 minutes to generate
required metadata for unfamiliar resources
Manually catalog by copying, pasting, and typing
while reviewing resource on-line
8
Decide what to catalog and how
DPC granularity recommendations:
Create single records for resources as a whole
- begin with overarching site.
Create additional records if individual parts of
resource differ substantially in technical
requirements, descriptions and educational data.
Strikes a balance between supporting resource
discovery with reasonable user effort yet avoids
potential user frustration with retrieving too many
redundant records – proposed hybrid discovery
system will help with this.
9
Consider user perspective
Think about end user, who will read your written
description and vocabulary choices.
What search terms would you use, if you were
looking for an item such as this?
What information would you need and want in the
description as a potential user of the resource?
Your characterization will assist users in finding the
resources they want.
10
Contribute a Resource
Click on “Catalog a Resource” then “Launch
the DLESE Resource Cataloger”
Activities supported:
Create new records
Edit records you have created previously but not
yet submitted
View best practice guidelines and view vocabulary
explanations for DLESE metadata
11
Navigation and Tech Tips
Only one instance open at a time
Navigation via side bar, no Back button; re-sizing
windows not recommended in Netscape 4.x
Best practices for each field available as link
Several types of data input…. Some require a submit
before leaving the page, others build lists.
12
Filters
Relevance Filter:
Is the resource relevant to Earth System Science
education?
Integrity Filter:
Does it function reasonably; i.e., seem to be
basically bug-free?
13
URL Field: The URL that resolves to the
resource.
Can only support http:// , not ftp or https protocol
Indicate the URL down to a file name like index.htm, if you
cannot determine the file name then include a trailing slash at
the end ( e.g. http://www.dlese.org/ )
URL is a string of 1024 characters max
Mirror sites can be indicated in the “ Additional Information”
entry field and added using XML
14
Find the file name
Tricks to finding the filename extension
index, welcome, main, default, home
htm, html
Open in new window, follow links noting
address in lower left of window
View ->Page Info in Netscape
15
Duplicate checking
If the URL is already in the DLESE collection you will
not be allowed to catalog it.
If it is similar in domain name you may decide to
catalog it if:
It really is a different resource under a similar looking URL.
If your URL is under a similar looking URL but differs
substantially in description, educational components or
computer requirements from the similar URL.
Don't catalog your URL if
It is a component of another URL and is sufficiently described
by that URL's catalog record.
16
Title: The name given to the resource by a
creator, publisher or cataloger
Use the title displayed on screen to the user, not the title in a
browser's title bar. Capitalize first letter of each word.
Specify subtitles within Title by inserting a colon and then
including the supporting phrase. Do not insert the word “subtitle”.
Spell out acronyms in titles.
Do not include alphanumeric references (GEO 101) in title, put
these in the description if appropriate.
If the creator or publisher does not supply a title, the cataloger
can provide one. Do this by including the following in Title: "(title
provided or enhanced by cataloger)".
17
Description: Narrative describing the content,
purpose, organization, or goal of a resource.
Critical free-text search field. Include information on
scientific concepts covered, pedagogy, and
implementation. Avoid too much redundancy with
other fields, if possible.
Use tables of contents, abstracts, outlines, indices
and descriptions to craft complete sentences that
describe the resource (re-format to reduce white
space).
Metatags may also offer starting points for crafting a
description
18
Description, continued
Do not need to include lists of housekeeping links
(Site Map, Contact Us), but rather summarize the
substantive materials that links point to.
When you are describing a model or simulation,
include information about the input and output
variables of the model or simulation.
Description is limited to 2048 characters max.,
including white space.
19
Description, continued
Compose in word processing environment to
facilitate spell-checking, formatting (delete
white space from captured text) and
character counts.
Avoid using & < > “ ‘ because these are
special characters in XML
20
Example Description
This is an interactive distance learning web site designed to
immerse you in the excitement of discovery and exploration
of the deep seafloor. Dive and Discover brings you on board
a series of research cruises to the Pacific and Indian
Oceans, and gives you access to the latest oceanographic
and deep submergence research as it happens. This site
allows you to join scientists who are exploring the seafloor
and making amazing deep sea discoveries. Current research
cruises are investigating the biological communities of
hydrothermal vents and the volcanic activity of the midocean ridge. The cruises use a variety of submersibles,
including Alvin, Jason and Argo.
21
Subject: The content area(s) of science and
learning addressed by the resource
Is used in the Browse histogram
Indicates distribution of resources across disciplines
Use a controlled vocabulary
Up to 8 but usually 1 to 3 will suffice
22
Resource Type: The educational type of the
resource with regard to how the resource may be used
in the classroom, professional development or in an
informal educational setting.
Use Resource Type up to 8 times to specify multiple instructional
types like activity, simulation, or answer key.
Resource Type has a controlled vocabulary to facilitate search &
retrieval.
Categories are: Audio, Data, Learning Materials, Portal, Service,
Text, Tool, Visual
Then choose a specific corresponding resource type from the dialog
box (e.g course, curriculum, scientific visualization, etc.)
Some Resource Types comprise others. Be careful not to
overcatalog.
23
Audience: The typical kind of learner(s) or
audience for whom the resource is intended. The
beneficiaries of the resource.
Use the controlled vocabulary to facilitate search and retrieval,
up to 8 items
