TopBraid EVN can manage an unlimited number of

vocabularies – that may be interconnected

(3)

Vocabularies can import one other, with each

vocabulary having its own set of permissions.

(5)

Depending on the level of access, users can

view and comment only or edit vocabularies

Concepts page shows a tree of concepts and the detailed view for each selected concept. It also includes a collapsible Search panel.

(6)

Concepts can be found easily using their preferred,

alternative or local language labels.

The example shows how a dropdown appears with auto-completion of the user’s entry

(7)

EVN provides a highly granular history and

keeps an audit trail of all changes

This example shows the history of changes for the ‘has broader’ relationship on

‘Prussia’. ‘Germany’ was added and

‘Europe’ deleted by the users shown below along with timestamps of the changes.

(8)

EVN supports rich text editing, adding images

and wiki-style text linking of concepts

This example shows how, in a rich-text field, a resource can be linked. For ‘South Georgia and the South Sandwich Islands’, a link from ‘United Kingdom’ in the text is being added to the concept ‘United Kingdom’.

(9)

EVN connects to popular Linked Data

sources such as DBPedia

1

2

DBPedia match is found automatically and stored in ‘has related’ field

(10)

EVN connects to any Linked Data source that provides

SPARQL Endpoint or URL dereferencing

All the property values from

external sources are copied. They are protected from edit and can be later refreshed on demand

(11)

EVN’s edit operations allow multiple

changes to be made at the same time

Several new concepts can be created at the same time

Other group operations include: merge and clone concepts and trees; find, replace and remove property values for groups of concepts

(12)

EVN’s edit operations allow multiple

changes to be made at the same time

Several concepts can edited at the same time. Newly entered values will be added to all edited concepts. Values common to all edited

concepts can be removed or changed at once.

EVN ensures information quality by enforcing

consistency and best practices through rules

SKOS rules are already provided for organizations wanting to use them (for example, alternative label can not be the same as preferred label). Any number of organization and content specific rules can be easily added.

(14)

EVN includes pre-built SKOS constraints.

Custom constraint rules can be added.

Check entire vocabulary Include pre-build SKOS constraints, or your own constraint rules

(15)

Concept Types page shows an overview of

types (classes) and their properties

(16)

New types can be added and information

about types can be readily edited.

(17)

An unlimited number of new properties

can be created for each type

This example shows adding a new attribute for the Concept Type ‘Country’

(18)

Forms on the Search panel enable concepts of interest

to be found based on their property values

1

Users can select which values to show as columns in the results report

This example shows a search for all the capitals of countries in Europe

Search results can be exported into Excel to

create custom reports and exports

(20)

Any item managed by EVN can have comments

with timestamps and user names

The example shows a comments being viewed and added

2

(21)

Vocabularies can have multiple

simultaneous versions or working copies

Working copies enable a review and

approval process before changes are

published. They also make it possible for

different teams to work in parallel.

(22)

A working copy of a vocabulary has its

own set of user permissions

Changes made to a working copy are

‘sandboxed’ and will not be applied to a

vocabulary until they are published by a

user who has the right to change the

vocabulary.

(23)

With parallel work, EVN users can see if changes they

are making will impact other working copies

1

The example shows a user working in the ‘Asia

Changes’ working copy of the Geography vocabulary. They want to see if any other working copy has changes to ‘Armenia’ concept

(24)

To support the review and approval process, EVN has a

variety of reports, such as a Comparison Report

(25)

EVN reports include generation of

vocabulary statistics

This graph shows the number of nodes at each level of a vocabulary hierarchy

This graph shows the distribution of children across concepts. For

example, there are 2 concepts with 13 children.

(26)

All content can be exported in RDF/XML and

Spreadsheet formats

All content can be exported in to a number of

formats
