Termín interoperabilita sa začal objavovať v súvislosti s nárastom informačných zdrojov a v súčasnosti jej otázky riešia pracovníci knižníc, múzeí, galérií aj archívov prakticky v každodennej práci. Pre dosiahnutie sémantickej interoperability takýchto zdrojov sa musíme sústrediť predovšetkým na dve kľúčové oblasti: metadátové schémy a pravidlá pre ich vypĺňanie a budovanie systémov organizácie poznania, súborov autorít a systémov, určených pre klasifikáciu zdrojov. V prostredí pamäťových inštitúcií v ČR patria práve knižnice k tým pamäťovým inštitúciám, ktoré so štandardizáciou na národnej i medzinárodnej úrovni začali ako prvé. Súčasné technológie spolu s existujúcimi medzinárodne platnými štandardami umožňujú vzájomnú spoluprácu nielen v rámci danej komunity, ale rovnako naprieč pamäťovými inštitúciami, čo umožňuje poskytnúť používateľom oveľa viac informácií z heterogénnych zdrojov a tieto navyše prepojiť na základe ich významu. V príspevku popisujeme infraštruktúru a rozširujúcu nadstavbu pre personálne autority. Toto riešenie bolo navrhnuté a realizované v rámci projektu "Národní autority v prostředí muzeí a galerií-interoperabilita s NK ČR". Rozšírenie metadátovej schémy pre personálne autority realizujeme v súlade s ontologickým rámcom CIDOC CRM (ISO 21127:2006), čím môžeme používateľom ponúknuť oveľa presnejšie, komplexnejšie vyhľadávanie, ale zároveň vytvárame základ pre prepojenie heterogénne budovaných fondov na základe významu informácií v nich obsiahnutých. V príspevku referujeme o praktických výsledkoch projektu, stručne tiež popisujeme veľmi úzko súvisiaci projekt-Registr sbírek výtvarného umění. Tento prezentuje verejnosti už viac ako 80 tisíc umeleckých diel zo zbierok galérií, združených v Rade galérií ČR. V závere nášho príspevku ponúkame niekoľko ďalších námetov pre využitie takto prepojených zdrojov s cieľom ponúknuť používateľom viac informácií a poodhaliť im aj viaceré znalosti, ktoré sa v týchto zdrojoch ukrývajú.

“…The concept of a repository for storing data is well developed in a range of fields, including the creation of digital libraries [58,59], education [60,61] and software development [62,63]. As product design becomes increasingly a global enterprise, the need for networked, collaborative tools to support design innovation has become more pronounced.…”

Without a doubt, the current generation of secondary school students is very familiar with information technology. Text messaging, e-mail, and social networking websites are a normal means of communication. There is also increasing recognition of the need for diversification the engineering workforce and increasing the number of graduating engineers in the United States. This has created an opportunity to leverage leading edge Cyberinfrastructure in an outreach program targeting secondary school students. This paper demonstrates the implementation of a targeted outreach program that engages high school students in engineering design over a two-week period using state-of-the-art digital design repositories and motion simulation equipment.

Crawling the Web to build collections of documents related to pre-specified topics became an active area of research during the late 1990's, crawler technology having been developed for use by search engines. Now, Web crawling is being seriously considered as an important strategy for building large scale digital libraries. This paper covers some of the crawl technologies that might be exploited for collection building. For example, to make such collection-building crawls more effective, focused crawling was developed, in which the goal was to make a "best-first" crawl of the Web. We are using powerful crawler software to implement a focused crawl but use tunneling to overcome some of the limitations of a pure best-first approach. Tunneling has been described by others as not only prioritizing links from pages according to the page's relevance score, but also estimating the value of each link and prioritizing them as well. We add to this mix by devising a tunneling focused crawling strategy which evaluates the current crawl direction on the fly to determine when to terminate a tunneling activity. Results indicate that a combination of focused crawling and tunneling could be an effective tool for building digital libraries.
