How NASA Mission Operations used a semantic wiki to solve its knowledge management problem. The EVA wiki makes our data more useful with semantic properties, queries, and integration with outside databases.

11. Proof of Concept
Copyright © 2014 by United Space Alliance, LLC
• Added
content
to
wiki
through
annual
proficiency
training
– Allowed
for
minimal
duplica/on
of

• Installed

– Shed

• A

was
presented
to
management,
once
cri4cal

was
achieved

12. Hurdles
Copyright © 2014 by United Space Alliance, LLC
• There
is
a
double
standard
for
wikis
– Wiki
makes
info
easier
to
access/edit/share
informa/on
• Ini/ally
this
was
viewed
as
a
nega/ve,
not
a
posi/ve
by
management
• Can
the
wiki
be
trusted?
– Sharepoint/word/PDF/
documents
were
just
as
vulnerable
to
revisions
or
access
control
issues

16. Mee/ng
Minutes
Copyright © 2014 by United Space Alliance, LLC
• Un/l
wiki
was
implemented,
Mee/ng
Minutes
were
captured
via
email
– Informa/on
was
lost
in
crowded
inboxes
– Cumbersome
to
search
• SMW
was
used
to
create
Mee/ng
Minutes
form
• Served
as
a
catalyst
to
get
new
users
involved
in
the
wiki
– Edi/ng,
