3. Mappings – Xpath mapping
3
 Xpath mapping is performed simply by dragging the xpath from the
input tree and dropping it to the desired element of the mapping
area.

4. Mappings – Enumerated
Mapping4
 Double click on an element that takes values
from an enumerated list.

5. Mappings – Constant Mapping
5
 By double clicking on the unmapped area you
can type a constant value that will be applied
to all items.

6. Mappings – Concatenate
mapping6
 By clicking on the icon you can perform a concatenate
mapping i.e. to combine more than one mappings for
producing a new mapping.

7. Mappings – Functional
Mappings7
 By clicking on the button you can perform a
functional mapping i.e. to modify the value of an
input xpath by applying a string manipulation
function to it.

8. Functional Mappings
8
 Substring – You set the start and the end index.
 Substring after – You set the substring of the original
string after which the value is taken.
 Substring before – You set the substring of the
original string before which the value is taken.
 Substring between – You set the substrings of the
original string after and before which the value is
taken.
 Split – You set the delimiter for tokenization and the
start index of the original string.
 Tokenize content and generate an element per
content – You set the delimiter for tokenization.

10. Mappings – Conditional
Mapping10
 Allows users to set conditions on their mappings
 If the value of xpath tns:Description contains “southwest”
then the value of the xpath tns:Description will be mapped to
the xpath edm:ProvidedCHO/dc:description of the target
schema.

11. Mappings – Value Mappings
11
 Allows users to map specific values of their
input metadata to specific values that they set.

12. Structural mapping
12
Reflects a complex type of the input metadata to a
complex type of the target schema

tns:ActorNam

13. Structural on any element

Reflects a complex type of the input metadata to an
element of the target schema

14. Thesaurus mapping
14
 Bookmarks have been created for the
elements that are controlled by vocabularies.

15. Thesaurus mapping
15
 Double click on an element that is
controlled by a thesaurus.

16. Thesaurus mapping
16
 The terminology browser pane appears.

17. Thesaurus mapping
17
 Navigate through it
 By searching for a
term
e.g. Jazz
 By using the hierarchy
 for more specific
terms (narrower)
 for less specific
terms (broader)
 Select the term you
like by clicking on it

18. Thesaurus mapping
18
 Instead of applying a value to your whole
dataset you can align your in-house terms
to vocabulary terms.
 First map the xpath that holds your in house
terms to an element that is controlled by a
vocabulary.

19. Thesaurus mapping
19
 After that, click on the
value mapping icon
(=)
 Select a term from
your metadata
e.g. Louis Armstrong
 Select a term from the
vocabulary
e.g. Jazz
 Click on the add
button to align them
