Efficient XQuery Support for Stand-Off Annotation
XML annotations are a widely occurring phenomenon in many application fields, and XML databases should be used to store and query such data. To provide intuitive and fast querying of annotations, we make a case for extending XPath with four new axis steps, that correspond with socalled StandOff joins, introduced here. The new steps can be efficiently implemented using a region index and fast lo...
متن کاملPractical applications of stand-off annotation
An information system that makes use of stand-off annotation stores metadata separately from the data they describe. System architectures separate metadata from data in order to cope with heterogeneous annotations or with multimedia formats. This paper discusses some of the practical aspects of implementing an information system with a stand-off architecture. Two systems that use stand-off anno...

متن کاملStand-off Raman spectroscopic detection of minerals on planetary surfaces.
We have designed and developed two breadboard versions of stand-off Raman spectroscopic systems for landers based on a 5-in. Maksutov-Cassegrain telescope and a small (4-in. diameter) Newtonian telescope receiver. These systems are capable of measuring the Raman spectra of minerals located at a distance of 4.5-66 m from the telescope. Both continuous wave (CW) Ar-ion and frequency doubled Nd:YA...
متن کاملStand-Off Biodetection with Free-Space Coupled Asymmetric Microsphere Cavities
Asymmetric microsphere resonant cavities (ARCs) allow for free-space coupling to high quality (Q) whispering gallery modes (WGMs) while exhibiting highly directional light emission, enabling WGM resonance measurements in the far-field. These remarkable characteristics make "stand-off" biodetection in which no coupling device is required in near-field contact with the resonator possible. Here we...
