eCHO: Enriching The Digital Representation of Cultural Heritage Objects

Requirements

JDK 11+ or OpenJDK 11+
Maven 3.x

Setup

1. Download and install JDK 11 or OpenJDK 11 (or newer versions)
2. Download and install Maven 3.x
3. Clone the repository:

git clone https://github.com/iliedorobat/enriching-cultural-heritage-metadata.git

4. The main language is set to Romanian language by default. If the dataset uses a different language, you must modify the LANG_MAIN environment variable located in EnvConstants.java.
5. Open the Terminal/Command Prompt and navigate to the root directory (enriching-cultural-heritage-metadata directory).
6. Generate the library:

mvn validate && mvn clean package

Collect museum datasets:

java -jar target/eCHO-1.4-jar-with-dependencies.jar --museumsCollector

Translate XML files to EDM:

1. CIMEC to EDM:

## main command
java -jar target/eCHO-1.4-jar-with-dependencies.jar --dataType=CIMEC
## quick demo
java -jar target/eCHO-1.4-jar-with-dependencies.jar --demo --dataType=CIMEC

2. DSPACE to EDM:

## main command
java -jar target/eCHO-1.4-jar-with-dependencies.jar --dataType=DSPACE
## quick demo
java -jar target/eCHO-1.4-jar-with-dependencies.jar --demo --dataType=DSPACE

3. LIDO to EDM:

## main command
java -jar target/eCHO-1.4-jar-with-dependencies.jar --dataType=LIDO
## quick demo
java -jar target/eCHO-1.4-jar-with-dependencies.jar --demo --dataType=LIDO

Normalize time expression

java -jar target/eCHO-1.4-jar-with-dependencies.jar --expression="1/2 sec. 3 a. chr - sec. 2 p. chr."

Input Datasets

CIMEC datasets:

• Datasets need to be added in the files/input/cimec directory.
• The existing datasets

DSPACE datasets:

• The datasets need to be added in the files/input/dspace directory.
• Snapshot of dspace storage level:

main_directory/
    item1/
        dublin_core.xml
        contents
        contentFile1.ext
        contentFile2.ext
        ...
        contentFileM.ext
    item2/
    ...
    itemN/

LIDO datasets:

• The datasets need to be added in the files/input/lido directory.
• The existing datasets have been downloaded from the data.gov.ro portal.

Output Datasets

CIMEC datasets: The output datasets are located to the files/output/cimec2edm directory.

• *.rdf contains the EDM prepared datasets;

DSPACE datasets: The output datasets are located to the files/output/dspace2edm directory.

• *.rdf contains the EDM prepared datasets;

LIDO datasets: The output datasets are located to the files/output/lido2edm directory.

• *.rdf contains the EDM prepared datasets;
• timespan_all.txt contains all identified time expressions;
• timespan_unique.txt contains unique identified time expressions;
• timespan_all-analysis.csv contains the pair of input time expressions - normalized centuries;
• timespan_unique-analysis.csv contains the unique pair of input time expressions - normalized centuries;
• properties.csv contains the pair of parent property - child property.

Online Datasets

• The output datasets are available on opendata repository and can be queried by using the opendata sparql endpoint.
