Semistructured data
, 1997
"... In semistructured data, the information that is normally as-sociated with a schema is contained within the data, which is sometimes called “self-describing”. In some forms of semi-structured data there is no separate schema, in others it exists but only places loose constraints on the data. Semi-str ..."

In semistructured data, the information that is normally as-sociated with a schema is contained within the data, which is sometimes called “self-describing”. In some forms of semi-structured data there is no separate schema, in others it exists but only places loose constraints on the data. Semi-structured
The Lorel Query Language for Semistructured Data
- International Journal on Digital Libraries
, 1997
"... We present the Lorel language, designed for querying semistructured data. Semistructured data is becoming more and more prevalent, e.g., in structured documents such as HTML and when performing simple integration of data from multiple sources. Traditional data models and query languages are inapprop ..."

Storing semistructured data with STORED
"... Systems for managing and querying semistructured-data sources often store data in proprietary object repositories or in a tagged-text format. We describe a technique that can use relational database management systems to store and manage semistructured data. Our technique relies on a mapping between ..."

Inferring Structure in Semistructured Data
- In Proceedings of the Workshop on Management of Semi-structured Data
, 1997
"... When dealing with semistructured data such as that available on the Web, it becomes important to infer the inherent structure, both for the user (e.g., to facilitate querying) and for the system (e.g., to optimize access). In this paper, we consider the problem of identifyingsome underlying structur ..."

Typechecking for Semistructured Data
- SIGACT News
, 2001
"... look for the tags they need, and ignore all the others. At a more detailed level, an agreement should also constrain the structure. For example a data item with a price tag must contain an integer value, while a data item with a product tag must contain nested items labeled name, price, and descrip ..."

, and description. An agreement on the structure enables applications to navigate the data in a meaningful way. We call a collection of constraints on the structure a type. Several type formalism have been proposed for semistructured data [BDFS97, GW97, BM99], and several are considered for XML [Con98, BLM + 99
Indexing semistructured data
, 1998
"... Abstract This paper describes techniques for building and exploiting indexes on semistructured data: data that may not have a xed schema and that may be irregular or incomplete. We rst present a general framework for indexing values in the presence of automatic type coercion. Then based on Lore, a ..."
