In this video I will introduce you to working with the editor.
We will perform different changes such as adding descriptions,
changing the preferred term,
and adding relationships to a concept
We will start with adding a new synonym.
I've already prepared.
a concept for you here
If you click the blue triangle,
A list with actions will come up that you can perform
and what we're going to do is -- we will just clone the synonym.
I just click > Clone here
and -- you see ---
the system creates
an identical
copy of
the previous synonym here, the one that I chose.
And it copies also all of the settings, for instance the
case sensitivity it's the same as
here above. Case sensitive and this one is case sensitive as well.
And
you see now here little
asterisk
indicates that we have made a change that hasn't been safed. You can also see
an informational message displayed: "Concept contains unpublished
changes"
and a little I icon here next to the
icon for organism appears that indicates
also that there are unpublished changes.
Now all you have to do it is type in your
new synonym. I will type "Hantavirus"
and hit the save button
and now you can enter the a commit comment. I will just write "Added Hantavirus synonym"
and click
okay
Now it's saved
and now that new description appears here.
It has a box around the term, this is because it's an
unpublished
change.
This means the change has been saved in the repository but not
formally published,
not been formally published yet.
Once a concept has been published only
the text appears so he won't see
this box
anymore.
You can also see my
change here and the commit information view,
you can see the date
when it was changed, you can see my user ID
and my commit comment that I typed in is displayed here
and the same in the history view:
you can see here -- I'm the author,
my comment and the date when it was
changed.
And down here you can see here that's a new
synonym
hantavirus that was added.
You can use the clone function whenever you have a description type
that is already there -- like synonym in this case
and
what is actually displayed here is specified by the
concept model -- I will talk a little bit more about this in the
properties section.
You also have the option to add
an unsanctioned description.
Unsanctioned means that it's not been sanctioned by the concept model,
but you can add it nevertheless and this is with this little icon here
in the toolbar.
If I click it
two entry boxes
will appear: one for the description type. and one for the description term
and if I
click
into this
Snow Owl will
automatically
give me valid description types that I can you use. So in this case it's
definition, fully specified name, or
synonym.
If you're wondering what these are. They are
in the description format here,
this is actually what triggers this so that they come up.
So you see here there are three different options
the description format is defined as plain text
and the maximum characters that you can enter for a definition are
1,024 characters and for fully specified name and for synonym
there are less characters, so they are shorter.
Let's go back
and
I want to add a definition
so you just click it
and I actually already
copied
something from Wikipedia that I will just
paste in here
for Hantavirus
so you see it's that's quite a long
definition
and then it's again like before, you just click the save button
and you can enter a commit comment
again
like
Added
definition
from
Wikipedia
and you hit Okay
and it saves it to the
repository.
Again you can't see the two boxes around it that indicate
that it's an unpublished change. So this is unpublished
the description type is unpublished and also
the definition
and the synonym that I
saved
earlier.
If I hover over it the tooltip appears that you might remember from
the previous video.
It shows the effect time
and it says "unpublished" because
the description has not been published yet.
So it's actually not the time from the commit information view
which is when I actually make the change
this would be the time of the
publication as you can see with the published
concepts here
and
something that is also different is the module it's the SNOMED CT
B2i extension
versus here it was the SNOMED CT
core
module
and
you can also see the description
is
case insensitive which is
the
default setting
for
unsanctioned descriptions. If I
copy a synonym then it will take the case sensitivity. This is case sensitive
and
if a copy this, it's case insensitive
this is why it's different
You can change it very easily if you want that
by going to this context menu
so you can set it to "case sensitive" or "initial character case insensitive"
whatever you'd like.
Now
i would like to show you how to change the preferred term of a concept. This is
quite easy. Let's go to a different concept, to this one
the preferred term is indicated by the little rosette icon so wherever this is,
this is the preferred term. If you hover over it you will also see
"preferred term"
displayed
and we want to change it from
"Calcific tendinitis of shoulder"
to "Milwaukee shoulder".
All you have to do is
click here the blue triangle again
and then there's an option that is set to Great Britain
preferred.
This means that to you set the selected description as the preferred description
for the currently
active language
dialect.
This is indicated that it's Great Britain by the British flag so if this was
Australia than it would have the Australian flag here and so on.
So if I
click this you see then the rosette icon
changed down here to
Milwaukee shoulder and its not saved yet. There is again a little
asterisk here.
And if I
save it I can
enter a comment which i'm not going to do now
and now it saves it
as the new
preferred term.
You can see here in the editor, it's not
"Calcific tendinitis of shoulder" anymore but it's "Milwaukee shoulder"
and
it also changed here in my SNOMED CT hierarchy.
Now it's
"Milwaukee shoulder"
so both of the terms
changed.
You might have already noticed that some of the actions here are disabled
for instance for the fully specified name I can
not "Clone" or "Retire"
i can only
"Clone and retire"
This is because it's
restricted
by the concept
model.
So it will only enable actions that are actually
allowed by the concept model.
For the fully specified name
the
IHTSDO editorial guide defines that a concept has
one -- and only one -- fully specified name,
one or more synonyms,
and one preferred term
and we implemented this rule in our Snow Owl concept model and therefore
you will always have
only one fully specified name,
at least one synonym, and one preferred term.
This is the reason why you can't
retire a fully specified name because there has to be
at least
one, has to be only one
and not two
and you can't clone it because there can't be two fully
specified
names
and this is why you can only "clone and retire" it there. This means that a new
copy will be created of the description
and it retires the previously published description.
We already talked about this bottom part of the
menu where you can see
which
case sensitivity
is set.
This is indicated by the little box around it here, so you can see here
"Initial character
case
sensitive" which means
it doesn't matter if the first letter is upper or lower case
but the rest of
that description is case sensitive.
So much about the description section. I'm just going to
close it
and let's go to the properties section. We call this properties section
and not relationships sections because it includes not only
SNOMED CT relationships
but also
datatypes like 500 in a 500 mg
capsule
for instance.
And when we designed Snow Owl we wanted to make it easy for
you to do editing
and for this reason you see all of these empty text fields
here.
They are automatically created because they're specified by the concept
model.
This has the advantage that you don't have to find out which properties
are appropriate for your selected concept
because the mandatory and the optional properties are already displayed in this
section.
Okay, now let's see how that works -- actually
of course the concept model can be customized for
your particular organization
and
the values that you can enter here
are also
restricted.
So the results that will come up
are like in the quick search, it's the quick search feature that you already
know from
up here
but the results are restricted to valid
values that actually make sense to enter and I'll show you what this looks like.
Let's
add the severity.
If I click into this field it will
bring up the quick search
and there are only
seven different options here for severity because the results are
constrained to the values that are valid for this
particular
property
and I'm just going to
pick one of them.
Let's use "mild"
and then you can save it again with the save button,
you have a comment
and
you can see now it has
the box around it.
It's been
committed to the repository.
Let's do it for something else, for instance "finding method".
If I click this field here
it will give me a lot
more options
over 53.000 -- so there are a lot of procedures here so
now it makes sense to use the quick search. if i look for
"radiography of the shoulder" and I just type in a few words it will give me this option
and I can click it
and now I can save it as well. So this is when the quick search comes in
handy. Your previous choices and bookmarks also displayed in this field.
The actions available are same as in the descriptions section.
You don't have the "case sensitivity" options because you have to
use existing concept so you won't be able to type in new terms but you
can also clone and retire.
Let's go to the last section which is the "SNOMED CT
properties".
There are just a few options here.
There's the "status", it can either be
inactivated or
deleted.
You can only delete concepts that haven't been published yet
so if i try to delete
this concept
I get this dialogue: "The requested component cannot be deleted".
So it has been releasing cannot be
deleted. So I can't do this.
What i can do is
inactivate it
and here it presents the inactivation plan
which shows all the different components that will be
inactivated it: So the concept itself, the descriptions, the relationships and so on
and you can also choose the reason for inactivation,
or the target component,
but i'm not going to do this now.
I'm just going to hit cancel.
You can also change the "definition
status" from
primitive
to defined or the "subclass
definitions" but those are more advanced topics and I just wanted to give you
the basics of editing here in this video.
So much about this and in the next video we will talk about
reference sets.
