Dei. XTo – Web Data Extraction Tool • DEi. XTo (or ΔEi. XTo) is a powerful web data extraction tool that is based on the W 3 C Document Object Model (DOM). • • It allows users to create highly accurate "extraction rules" (wrappers) that describe what pieces of data to scrape from a website. DEi. XTo can contend with a wide range of digital libraries with high precision and recall. DEi. XTo is able to transform the contents of your digital library into OAI-PMH ESE or another suitable format. Visit: http: //www. deixto. com The Hellenic Aggregator

Open Archives Engine • Open Archives Engine (OAE) is a serverside software capable of creating a digital library metadata aggregator and search portal using OAI-PMH enabled, web accessible digital repositories • OAE utilizes the OAI-PMH protocol in order to retrieve metadata from multiple digital libraries and create an index which then can be used not only to search and filter information but also to export information in a variety of formats such as OAI-PMH Dublin Core (DC) and Europeana Semantic Elements (ESE). • OAE leverages the technology of Dei. XTO. The combination of OAE and Dei. XTO can extract metadata from any web accessible digital library regardless of the technology, it uses and make it available through the web interface or the web service. • Visit: http: //openarchivesengine. com The Hellenic Aggregator
