METADATA STRUCTUREHow to define/organize it

CONTROLLED VOCABULARY

• A controlled vocabulary is a glossary designed to allow knowledge organization in order to optimize information lookup/search.

•Classification schemes (taxonomy, thesaurus, ontology) use a controlled vocabulary.

TAXONOMY

• Subsumption relationship “is-a”

• Transitivity

• If C is a B and B is an A, C is an AVehicules

Land Vehicules

Car

Truck

Bus

Air Vehicules

Airplane

Balloon

Rocket

Sea Vehicule

Boat

Submarine

THESAURUS

• Taxonomy++

• Hierarchy + propertiesConept or potential term Car

Generic Term Véhicule

Specific Term  

Domains vehicule - transport [MT 3330]

Regional variations  

French equivalent voiture

Associated Terms [TA] craft : transport [MT 6005]automobile technic [MT 3510]

ONTOLOGY

Partitive relationships: Part-whole (car, chassis, wheels, engine) Composite-component (steel, iron)Content-container (tools, toolbox) Membre-collection( football player, team).

Associative relationships :Cause-effet (detonator, explosion)Agent-action-result (drawer, drawing) Producer-product (waste site, recycled product) Tool-tool (scewdriver, screw) Topologic relationships (oasis, desert).

ONTOLOGY OF A CAR

FOLKSONOMY

• Comes from “folk” (people) and “taxonomy”. Indexing spontaneously by keywords without pre-defined classification.

• This process is collaborative. (sometimes also called social tagging)

FACETS

•Description of a resource following multiple axes

•Allows you to search/refine by facet

CONCEPTS

• Term = denomination + concept

• Denomination = linguistic expression

• Concept = meaning

• The term has to have a context to understand the concept

• Ex table• Coffee table?

• Table of content?

• Timetable?

• Discussion table?

NAMED ENTITIES

•Main types of entities•Person’s names

•Places

•Organizations

•Products

•Dates

•Currencies

RECAP

Schema Taxonomy Thesaurus Ontology Folksonomy Facets

Organization

Simple hierarchical relationships

Hierarchical relationships (hyponymy, hypernymy) , associative relationships and equivalent relationships

Concepts with types, properties and relationships

Tags set by users as the like

Allows to describe a resource following multiple azes

NOT SLEEPING YET?Good let’s talk about SharePoint now

SHAREPOINTWhat can it do for you?

FOLDERS

•A folder structure is already a form of metadata

•Very simple to set up

•Complicated to change

•Trick•Don’t use it unless you have permissions related needs

TAXONOMY

•Advantages:• Search

• Filtering

• Advanced control

• Consistency

•Disadvantages:• Takes time to set up

•Tips:•Use most issued search requests to improve it!

•Delegate management of some branches

• If you don’t have a clear idea yet, use folksonomy

ENTERPRISE KEYWORDS

•Advantages:• Easier fro end users

• Takes into consideration keywords inside of documents

•Disadvantages:•Harder to manage

•No context during indexation

FOLKSONOMY

Content « like »Tagging (with user’s words)

NotesUser Profile

Filtered NavigationSearch refiner

Topics and power users to followDeprecated on SharePoint online!!!

DOCUMENTS SETS

« this document is related to that other one »Creates a documents « group » modelProperties can be common or individual

Trick:Can also be used for security purposes (not primary role)Don’t hesitate to create new content types inhereting from it

COLUMNS AND CONTENT TYPES

• Information about what the content is (CT)

• Adds properties (columns)

• Allows filtering, refinement, search….

• Allows to have multiple entry forms(CT)

NAVIGATION BY TAXONOMY

• Enhances nvigation

• Prepares users to use refiners

• Easy to set up

• Is a great alternative to/transition from folders

WIKIS

• Quick pages creation system

• Allows to link web content

• Advantages:• Very easy and fast to set up

• Disadvantages:• No advanced publication features

SEO/WEB METADATA

• By default SharePoint pages include little metadata (search engines)

• Publishing + 2013 allows us to provide more data• Description

• Keywords

• Sitemap

• Author

• Browser title

• …

FACETS

• Improve search

• Located on the left with search results

• Use metadata (all)

• You can (must!) customize it

• Very efficient to filter out not relevant data and drill down to the right result

DOCUMENT CENTER

•Organizes content with taxonomy• Drop off library

• Applies governance rules based on taxonomy

SITE METADATA NAVIGATION

•Build top navigation + urls with taxonomy

•Useful for SEO

•Great to build a portal in a “semantic” way•Structure depends on your thesaurus

OTHER METADATA

• Author

• Security

• Views (count)

• Containers (sites, doc libs…)

• Resource type (extension, mime)

•Dates (creation, modification…)

• Status (approval)

OK, WE GOT ITBut what is this all about?

WHAT’S THE POINT?

The general idea is to have a precise representation and a good structure of the ideas of

the company

Copyright Vincent BIRET ;-)

YES BUT!

Users never fill up metadata!

Solutions:

Index their salary on metadata fill up rate

Wall of shame of worst metadata “filler” of the company

Automate that part!

GRAPH? DELVE?Only buzz words?

GRAPH

• First of all it’s a mathematics model• Nodes, edges and by transivity “routes”

• Then data model• Idea that on piece of data is related to another

• Finally Microsoft is making huge investments for businesses• Actors, signals, objects

• Schema is extensible to add METDATA!

DELVE

It’s only one of the clients

DEMODelve portal

WHAT’S THE IDEA?

• Pro-active content

• Discoverability

• No need to search for something anymore

• If we still need to search something, way more efficient

• Make you save time, therefor money

CONCLUSIONTime to say good bye :’-(

CONCLUSION

•We improved navigation

•We improved findability

•We improved discoverability

•We improved user experience

•Everybody saves time

•The company saves money
