After performing a search, you may want to see more information about a data object. Notice that in your search results, some of the columns contain information marked with blue text. This text links to the “Data Landing Page” for a selected data object. A Data Landing page provides a detailed summary of an object, with links that enable further data exploration. The number of KBase data types that have Data Landing pages is increasing rapidly.
Since Data Landing pages open in another tab in your web browser, you can move between search results and Data Landing pages simply by clicking your browser tabs.
Within the Genomes category, the Scientific Name links to the Genome Data Landing Page for each organism. In the table listing genomes from your “arabidopsis” query, click on Arabidopsis thaliana to access the Data Landing page for this organism. Note that it can take a while for all the data in the Data Landing page panels to load.
This screenshot captures only a few of the panels available on the Data Landing page for this genome. Note that each panel is labeled with “kb|g.3899,” the KBase ID for the Arabidopsis thaliana genome. All panels can be moved around the page, removed completely or collapsed by hovering your cursor over the upper right corner to reveal the close and collapse buttons. These options allow you to customize the layout of the Data Landing page you are viewing.
Some panels on this page, such as the Genome Overview, are populated using information from the object. Others contain additional organism information that KBase pulls from external sources like Wikipedia. Several panels in this view may be empty because they are meant to hold information created and owned by a user. For example, scroll down and locate the Taxonomy panel.
If signed in, you can launch a new Narrative from this panel to build a species tree for the Arabidopsis thaliana genome and run other KBase apps and methods on this data.
Additional panels on the Genome Data Landing page let you browse and explore information about the organism’s contigs and gene list (see image below of the Contig Browser). You can also view a Publications list that provides journal, author, date, and title information. Titles are linked to the corresponding PubMed abstract, which can be read on the Data Landing page itself by hovering over the title.
In addition to organism information, a Genome Data Landing page also has panels that track how you and others are using that genome in KBase. For example, notice the panels on the Arabidopsis thaliana page that show which Narratives the genome appears in, who in KBase has used the genome, and a list of data objects referencing the genome. These panels are included on every type of Data Landing page, not just Genomes.
Also, an Object Reference and Provenance Graph at the bottom of the page gives a visual representation of the history and activity of a data object in KBase. Planned for every Data Landing page, these visualizations are interactive, allowing you to hover over portions of the graph to see object details and provenance information and to adjust the view of the graph to center it around a selected object. The Arabidopsis thaliana graph is relatively simple, but the screenshot below shows the provenance of a data object (a Rhodobacter genome) that has been used in numerous KBase analysis steps.
Although the Genomes category contains links to only Genome Data Landing pages, other data categories may contain more than one Data Landing page link. For example, results in the Genome Features category have links to Data Landing pages for Features as well as Genomes.
To explore the Data Landing pages for Features, return to the web browser tab that has your search results. In the category navigation options on the left, choose “Return to All Categories” and then select “Genome Features.” Notice that, in addition to the Scientific Name column, the Feature ID column links to Data Landing pages too.
Click the first entry in the Feature ID column to view the Data Landing page for a Locus Feature. Notice that the set of panels displayed on the Locus Feature Data Landing page differs somewhat from the panels on the Genome Data Landing page. For example, the Feature Data Landing page has a Biochemistry panel in place of the Taxonomy panel that is found on Genome Data Landing pages.
