Application-level Services for the Digital Cultural Heritage community include online services and workflows able to pre-process and visualize data in an automated manner.
The following services are available to the community:
Clowder
Clowder is a research data management system designed to support any data format and multiple research domains. It contains three major extension points: pre-processing, processing and previewing. When new data is added to the system, pre-processing is off-loaded to extraction services for extracting appropriate data and metadata. The extraction services attempt to extract information and run pre-processing steps based on the type of the data, for example to create previews. This raw metadata is presented to the user in the Clowder web interface. Users can upload, download, search, visualize and get various information about these data. Data in the case of VI-SEEM and more specifically in the field of Digital Cultural Heritage can be of very diverse types and formats. More specifically users can upload massively or individual files of:
- 3D Models: where extractors clean up and prepare for visualization on the platform itself.
- Scanned books and their metadata: OCR algorithms will be used to extract the text in the documents so that users can find books using both metadata information and the book’s contents.
- Image, text and sound files and their metadata, organised in collections.
- Advanced documentation data, such as Reflectance Transformation Imaging, and analysis of material properties of structures, works of art and artefacts.
CHERE
CHERE (Cultural HEritage REpository) is a collection of individual applications and services aimed at simplifying the handling of digital cultural heritage resources. It currently consists of module for repository and management of entries (based on Omeka-S), module for structure-from-motion reconstruction (based on VisualSFM, vlfeat,PMVS/CMVS, SPSR and texrecon) provided as both hosted web service as well as semi-automated Docker container, measurement module and web based module for basic editing of 3D meshes (Meshlab.js). It also provides basic tools to generate web based panoramas from 360 photos (pannellum). CHERE provides the following features:
- Structure-from-Motion reconstruction of 3D objects (online service and docker container)
- Online 3D mesh editing and measurements
- Generate progressive 360 panoramas from equirectangular 360x180 photos
- Management of digital cultural items and item sets
MC4CH
MC4CH (Management Cloud for Bulgarian Cultural Heritage) is a web-application service providing geographical information for Bulgarian Cultural Heritage in Cloud. This service was created based on Arches software platform - an open-source, geospatially-enabled software platform for cultural heritage inventory and management. It has been purpose-built for the international cultural heritage field, and the off-the-shelf or default version is configured to inventory and document all types of immovable heritage, including buildings, cultural landscapes, heritage ensembles or districts, and archaeological sites. Additional APIs which were integrated in this service are Django webserver, Postgres/PostGIS and some python packages. MC4CH provides the following features:
- User-friendly web interface that allows connection from any web browser
- The archeological places are visible using google map by zooming.
- Online searching different archeological places.
- Drawing by different markers.
- Add directions: Easting/Northing: See geographical position – longitude/latitude.
