Aims. We present a high quality multiwavelength (from 0.3 to 8.0 μm) catalog of the large and deep area in the GOODS Southern Field covered by the deep near–IR observations obtained with the ESO VLT. Methods. The catalog is entirely based on public data: in our analysis, we have included the F435W , F606W , F775W and F850LP ACS images, the JHKs VLT data, the Spitzer data provided by IRAC instru...

We present a public catalog of galaxy groups constructed from the spectroscopic sample of galaxies in the fourth data release from the DEEP2 Galaxy Redshift Survey, including the Extended Groth Strip (EGS). The catalog contains 1165 groups with two or more members in the EGS over the redshift range 0 < z < 1.5 and 1295 groups at z > 0.6 in the rest of DEEP2. 25% of EGS galaxies and 14% of high-...

Electronic B2B marketplaces bring together many online suppliers and buyers, each of which can potentially use his own format to represent the products in his product catalog. The marketplaces have to perform non-trivial mappings of these catalogs. In this paper, we analyze the problems which occur during the integration, taking several leading XML-based standards as an example. We advocate a t...

Given that e-catalogs are often autonomous and heterogeneous, effectively integrating and querying them is a delicate and time-consuming task. More importantly, the number of e-catalogs to be integrated and queried may be large and continuously changing. Conventional approaches where the development of an integrated e-catalog requires the understanding of each of the underlying catalog are inap...

This paper proposes a new approach t o solve the data inputting bottleneck problem f o r library catalog data, or metadata. T h e data have been provided with paper cards arranged in wooden boxes. A lot of efforts have been taken to digitize t h e m in order to put these data to be machine-readable. However, despite such effor t s , only a small amount of data has been digitized so f a r becaus...
