Mappings – Xpath mapping3

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

Mappings – Enumerated Mapping

4

Double click on an element that takes values from an enumerated list.

Mappings – Constant Mapping

5

By double clicking on the unmapped area you can type a constant value that will be applied to all items.

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.

Mappings – Functional Mappings

7

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.

Functional Mappings8

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.

Mappings – Conditional Mapping

10

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.

Mappings – Value Mappings11

Allows users to map specific values of their input metadata to specific values that they set.

Structural mapping12

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

tns:Actor

tns:ActorName

Bookmark: Subject Actor

edm:Agent

skos:prefLabel

Structural

Mapping

Structural on any element13

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

Thesaurus mapping14

Bookmarks have been created for the elements that are controlled by vocabularies.

Thesaurus mapping15

Double click on an element that is controlled by a thesaurus.

Thesaurus mapping16

The terminology browser pane appears.

Thesaurus mapping17

Navigate through it By searching for a

terme.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

Thesaurus mapping18

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.

Thesaurus mapping19

After that, click on the value mapping icon (=) Select a term from your

metadatae.g. Louis Armstrong

Select a term from the vocabulary

e.g. Jazz Click on the add button

to align them
