Education Metadata
Metadata why do I care?
why do we need a standard?
Recipe- all the different items that are part of the thing
we are creating—standards about describing nutritional information of the
recipe –this is metadata
Data-the book itself
Metadata for books—the title, author, length, readability
LRMI standardization of the metadata and how it is useful
AEP role-
Provides representation and insight on the LRMI TWG, oversee
communication outreach to educational resource community
So what
Existing metadata standards now includes IEE LOM, Dublin
Core Metadata, SCORM, Our own metadata schema
Why another standard—LRMI—to make it easier to find the
resources—accessibility, the availability of curriculum, international
baccalaureate
SCHEMA.org
international-need a standardized, centralized to use metadata to search
beyond education
Leverage this to make the data findable, makes its way
through the internet, need standaraized ways to find it
Need a common set of descriptors, common is not common
Education benefits by not going it alone but leveraging an
existing industry-publishing
Allows conversation between stakeholders
Internet makes it more diffiuclt-various standards meet each
other where they wouldn
‘t have in the past
LRMI—the future of education research

Find overwhelming results, a million results, frustrating,
takes too long to find what learners need, have to look through things to find what they really want by combing through
results to find what they need
Learners spending too much time searching, not enough time
learning or teaching. To be able to sort
by grade level etc helps all
Focused on making educational and research resources easy to
find
Coled with CC
Standard metadata framework for all educational content
Encompasses most common and often used key terms and filters
If adopted by major search engines, these will appear on the
browser screen when educators and students are searching to help them get the
exact information they need when they are searching
Get less results, but they mean more
Learning Resource Metadata Initiative
Recognize that publishers are helping in the discovery of ed
res and the marketing and awareness and commerce.
LRMI changing the world
Process of describing the resource in terms of the sets of
tags, then publishing that in a number
of formats depending on where it is being used (adopted by google, yahoo,
bing) making it evident where it is,
making it discoverable
TAG ME <FIND Me> LRMI
Open source taggers, open source within own toolsets
LRMI enable better search
Potato salad search-set of metadata that come up in google
without mayo etc. imagine these
happening within education—child ages 10-12, fractions, remediation?
Not for classes necessarily, but personalizable and
individualized
Resources more easily found and more easily used
Enables better search
Fractions search, new version too available now
Learning Media
New Zealand largest ed publisher, print and digital company
is gov owned, one of key clients is ministry of ed in NZ
Also global publisher and developer
Developed and host of largest metadata portal in NZ- hub for
all NZ
Market drivers-deliver profit, deliver future and digital
future, growth,
Teachers need relevant resources, need to find info at the
click of a button
Product perspective-plethora of computer disks in market,
Plethora of competitors, teachers can’t review all of these
that are not relevant
Relevance
Discoverability
Accessibility
Channels and
Teachers and learners need to know searching yields relevant
resources
Metadata—discoverability, relevant and accessible
Changes the way publishers stay relevant and
Bridging gap between publishers and educators
Challenges- search engines not structured for educational
resources
No education schema for metadata, makes it a hit and miss
chance to be hit by search engindes, difficult to clink up and browse
Can now provide structured linking and browsing, resources
better aligned for common core standards, other standards internationally,
better engaged educators who can discover relevant accessible resources easily
With no metadata, many resources are not discoverable within
sear ch engines, when metadata is embedded, more tags come out and the
resources become more discoverable
LRMI embeds more detailed tags in leveling, curriculum and
standards alignment
MICRODATA reveal—a better tool for testing, displays the
metadata in a table for display
LRMI enables: search
tools, integrated search, integration of catalogues of products, individualized
learning, and much more
Imagine a resource that rolls up when other searches are
coming through, can find aggregated materials,
Progressive manner for using LRMI
The Gates foundation has funded the shared learning
collaborative that is based on LRMI and also uses PARADATA which is meta
metadata
SLC
Creates chsared data searches, Makes data speak the same
language, opens the door to creating customizable learning maps and curriculum,
plans for students, turn flood of assessment and formative data into actual
insight and give students what they need in real time
SLC-cloud based data store, standardized metadata tagging
language, open license API for building software applications that actually
work together
More schools, better integration, and more data for everyone
Teachers can be free to teach, developers work SHARING
Making better tools for teachers and learners
Creation and movement toward digital assets—LRMI plays a role
to help developers to represent their resources, and to think differently about
their workflow and products
LRMI and SLC—set of repositories of data, being able to
coals those
Phase 1—
Development of specification, finding the learning objects
within these specificiations by Jan 2012
Final review now
LRMI properties, learning resource or not, 6 directly at
education—intended user, ed use, time required, age ranbe, interactivity, type
of resource, competency and assessment
Common set of recommended values- ~300 developed in this
set, will evolve over times, presentation, type, activity, etc.
Phase 2—proof of
concept
Interactivity with the users, as we are tagging, how is it
used, awareness building, collaboration of taggers and search, educator
publisher surveys, encouraging/supporting schema.org adoption—will be turned on
by next summer, then can filter by those attributes
PoC round one participants
PoC round two participants—22 actively pursuing phase 2
700+ resources already submitted for phase 2, 16 new
publishers in phase 2
PoC next steps
Continuing to tag additional resources from publishers
Document best practice tagging steps
Generate recommendations for feature/function requirements
for next gen tagging tools
Create service providers kit with services
Increase number of participating publishers
Shift from doing tagging to support publishers tagging
Goal is to make it easier to use,

Languages for metadata-localized in the US right now, in
English, will be localized, there is a mapping to grade level, have a shema in
any national organization around those pieces
Will work in standard browsers, google serves up different
browsers geographically
Education LRMI not yet being served, by summer 2013
Content management systems- using to do mapping, can create
an export, html microformat, fairly simple, limited fields
Does not address needs of higher education, only primary and
secondary schools, higher ed use cases are completely different
How will ranking occur?—LRMI will not be part of the
ranking, schema.org allows providers to come together to present, how it is
decided to monetize it or rank it, we can’t use it, LRMI filter should be
bringing better resources to the top
Creative Commons- works with open ed resources, license
models for open ed, how to identify resources on the web and manage those
resources
AEP and CC relationship balances the LRMI
In English now, math and language arts
Later will go into science and then social sciences, broader
group around implementation of LRMI (spec has only been around for less than a
year now)
