3D Models as spatially organized archives

3D data are more and more adopted (both fromdigitization and abstract modeling)

Models must enable synoptic view ofheterogeneous data, analysis, simulation...

Very useful feature: link to multimedia sources /documents or metadata related both to the modeland the reconstruction process

E-Publishing: new tendencies


[email protected]

“Traditional” E-Publishing

PDF Documents / Flash Pages / HTML Hypertexts(+ Images, Videos..)

Distributed through Web-press / RSS aggregators(like Google News - free contents / Newspass -pay-news)

Scientific contents: specialized Web-magazinesand portals

More complex data (e.g. 3D Models or culturalobjects) are usually indexed through theirmetadata (RSS or other syndication standards)

New tendencies: a “Post-literate age”

Post-textual communication (icons,videos, images, tags): plain text is NOT the maininterface

Tactile, customizable, mobile interfaces(Smartphones, iPod, Kindle, iPad...)

Mashups: integrated geo-information, tagclouds, augmented reality, 3D contents ...........

Access and contribution model

Access to 3D collections is usually in two steps:

1) Simple preview of metadata, access to additionalcontents and/or screenshots from the model

2) Download OR Interactive Visualization of the model,after installing a plug-in component andauthenticating

Contributors can be registered users of the website/systemor partners of the project.

Conclusions

Scientific metadata archives are convergingtowards 3D (e.g. Carare for Europeana)

3D Web quickly developing

Emerging tool: 3D Repositories (aestheticpurposes or specialized object collections)

CH 3D Repositories allow connection to metadataand multimedia documentation

Most oriented to a collaborative model enhancinguser generated contents, community-building andopen source resources.

3D Repository can turn out to be an effective toolfor collection, dissemination and publishing of
