However, the sheer number of resources makes it unrealistic to link them all in a centralised manner. Instead, search engines to find information in those resources flourish, and formal languages like Resource Description Framework and Web Ontology Language are increasingly used to allow linking of resources. A recent development is the use of userscripts to change the appearance of web pages, by on-the-fly modification of the web content. This opens possibilities to aggregate information and computational results from different web resources into the web page of one of those resources. Several userscripts are presented that enrich biology and chemistry related web resources by incorporating or linking to other computational or data sources on the web. The scripts make use of Greasemonkey-like plugins for web browsers and are written in JavaScript. Information from third-party resources are extracted using open Application Programming Interfaces, while common Universal Resource Locator schemes are used to make deep links to related information in that external resource. The userscripts presented here use a variety of techniques and resources, and show the potential of such scripts. This paper discusses a number of userscripts that aggregate information from two or more web resources. Examples are shown that enrich web pages with information from other resources, and show how information from web pages can be used to link to, search, and process information in other resources. Due to the nature of userscripts, scientists are able to select those scripts they find useful on a daily basis, as the scripts run directly in their own web browser rather than on the web server. This flexibility allows the scientists to tune the features of web resources to optimise their productivity. The web has seen an explosion of chemistry and biology related resources in the last 15 years: thousands of scientific journals, databases, wikis, blogs, and regular HTML pages are available containing information relevant to chemists and biologists. While each of those resources is valuable in itself, integrating information from these resources increases the value even more: for example, PubChem provides a wealth of data but could be complemented with 3D models to create an even richer information source. The original goal of the world wide web was to hyperlink individual web pages allowing humans to explore a web of knowledge. For individual web pages these links can be created manually, as is still done in blogs, wikis, and static HTML pages for large databases this is, however, not feasible.

Userscripts are small programs that can alter the HTML content rendered by web browsers.

For example, a userscript may add book prices from competitors to the website, or may remove unwanted advertisements from a site. Using the same approach, userscripts can also solve the problem of interlinking web resources, by adding to web pages of one resource dynamically generated hyperlinks into another.

For example, userscripts have been used in bioinformatics to enhance the iHOP web page : the script extracts user assigned tags from a third party resource, and shows them as a tag cloud on iHOP pages for particular genes.Īutomatic hyperlinking is only possible though the use of unique identifiers such as the PDB ID, the CAS registration number and, more recently, the IUPAC International Chemical Identifier (InChI).īy selecting a specific set of userscripts, the user can tune a website to provide all kinds of facilities not anticipated by the original author of the site.

While identifiers are easily used to connect databases, such as done in the SRS system or in meta database software like BioWarehouse, the sheer number of web resources makes it impossible integrate all resources. #Userscript di google book downloader software #Userscript di google book downloader registrationĬonsequently, (bio)chemical search engines, such as ChemSpider and tools to harvest information from web resources, such as ChemXtreme and BioSpider, as well as systems that standardize algorithmic access to resources and services, such as BioMOBY, have emerged.Īnother reason why identifiers do not always allow linking resources is that many of them are database specific, such as the PDB ID and the Digital Object Identifier (DOI), and sometimes even restricted in being used, as with the CAS registration number. Open standard identifiers address this problem.
